Event and Sponsorship IP Checklist: Mark Filings, Sponsor Exclusivity, Venue and Ticket Terms, Athlete Rights, and Ambush Monitoring

By Casey Scott McKay · 2025-02-18

This checklist runs an event intellectual property programme against the calendar, because every protection worth having has a deadline before the event begins. It opens with the mark portfolio and the official designations that are the sponsorship product, then drafts category exclusivity with the adjacency, portfolio, and acquisition clauses that prevent sponsor-versus-sponsor disputes. It works venue perimeter control, clean zone negotiation at bid stage, ticket and registration terms that are properly formed, and participant agreements including the personal-sponsor window that is the only route to addressing athlete ambush. It covers broadcast adjacency, the counterfeit programme that must run months ahead, monitoring with a named approver and pre-cleared letters, and an enforcement triage that separates the actionable from the lawful. It closes with the post-event review.

Boxes marked [Gate] must clear before announcement, before sponsor agreements are signed, or before the event opens.

The matter. The competitor bought every billboard around the stadium and ran a campaign about supporting the players. No marks, no sponsorship claim, no clean zone. There was no claim — and the following year the perimeter media was under first refusal and the ambush did not recur.

Phase 1. Mark portfolio

[ ] [Gate] File on intent to use under 15 U.S.C. § 1051 as soon as the name is settled and before announcement.
- Why. Event names leak through bid and procurement processes, and priority is inexpensive relative to a rebrand.
[ ] Register the composite logo, which is the strongest asset because the name is usually descriptive.
[ ] Register the event name, with an acquired distinctiveness argument prepared where 15 U.S.C. § 1052 applies.
[ ] Register coined names and taglines where they function as source indicators.
[ ] Register mascots, trophy designs, and the distinctive visual identity separately, and note each is also protectable by copyright as artwork.
[ ] Register year and edition composites, which support merchandise enforcement for a specific edition.
[ ] Cover the classes: entertainment and sporting services; clothing; printed matter; toys and games; souvenirs; downloadable and virtual goods.
[ ] File in home, host, and broadcast markets.
[ ] [Gate] Do not assume special statutory protection.
- Trap. 36 U.S.C. § 220506 is a specific grant for Olympic symbols with no general equivalent, and it is cited constantly by organisers who do not have it.

Phase 2. Official designations

[ ] Identify every designation the sponsorship programme will sell: "official sponsor," "official supplier," "presenting partner," and category-specific formulations.
[ ] [Gate] Register them, because they must be owned to be licensed.
[ ] Publish usage guidelines specifying approved forms, placement, and prohibited variations.
[ ] Confirm no two sponsors hold designations that overlap in claim, even where the product categories differ.
- Trap. A bank and an insurer both claiming an "official financial services" designation, which is a claim conflict rather than a product one.
[ ] Confirm designations are used in the approved form by each sponsor, and enforce against sponsors as well as outsiders.
- Why. The organiser's own sponsors are the most common source of designation misuse.
[ ] Include designation rights expressly in the sponsor rights schedule.
[ ] Reserve the right to withdraw a designation on breach.

Phase 3. Base mark maintenance

[ ] [Gate] Confirm the base marks are alive and in use between editions.
- Why. Organisers register the current edition's composite and let the base marks lapse in the interval, then find a squatter has filed. This is the most common portfolio failure in the practice.
[ ] Diary declarations under 15 U.S.C. § 1058 and renewals.
[ ] Confirm actual use between editions, so the marks are not vulnerable to cancellation for non-use under 15 U.S.C. § 1064.
[ ] Maintain merchandise or licensing activity that supports continuing use in goods classes.
[ ] Set a watch service for confusingly similar filings, including squatter applications in host markets.
[ ] Review the portfolio annually against the coming edition's markets.
[ ] Record marks with customs in every merchandise market and keep the recordations current.

Phase 4. Category exclusivity

[ ] [Gate] Define each category by product and claim, not by industry label.
- Trap. "Beverages" is not a category. "Carbonated soft drinks, excluding energy drinks, bottled water, and juice" is.
[ ] Include an adjacency clause stating which sponsor holds contested boundary products.
[ ] Include a portfolio clause stating whether exclusivity attaches to the group or to the contracting entity and named brands.
[ ] Include an acquisition clause stating what happens if a sponsor acquires a business in another sponsor's category during the term.
- Why. This occurs regularly and leaving it to a dispute is worse than any outside ambush.
[ ] Check for designation conflicts across categories, not only product conflicts.
[ ] Confirm no category promise exceeds what the organiser can actually control.
[ ] Circulate the full category schedule internally, so sales does not sell an overlapping right.
[ ] Review the schedule before each renewal cycle, since sponsors' businesses change.

Phase 5. Sponsor rights schedule

[ ] Specify mark and designation use, with approved forms and usage guidelines annexed.
[ ] Specify activation space, its location, and its dimensions.
[ ] Specify hospitality allocation.
[ ] Specify broadcast inventory, and whether the organiser can actually deliver it.
[ ] Specify digital and social inventory, distinguishing what the organiser controls from what the venue and broadcaster control.
[ ] Specify athlete access and its limits.
[ ] Specify data and audience rights, subject to privacy obligations that constrain what can be granted.
[ ] Specify right of first refusal on renewal.
[ ] [Gate] Specify expressly what is not granted: the right to prevent lawful thematic advertising, references to the sport or the city, or a competitor's association by proximity.
- Why. An agreement implying otherwise creates a claim against the organiser.

Phase 6. Ambush obligations

[ ] Commit to a monitoring programme with defined scope and a start date.
[ ] Commit to defined enforcement steps on identified conduct, within a stated response time.
[ ] Commit to procuring, or granting a right of first refusal over, perimeter and transit advertising inventory.
[ ] Commit to using reasonable endeavours to procure and enforce a clean zone, where the organiser has that leverage.
[ ] Attach a remedy — fee reduction or make-good inventory — if the obligations are materially unmet.
[ ] [Gate] Carve out conduct that uses no marks and makes no representation of association.
- Why. No organiser can prevent lawful thematic advertising, and promising to is how a commercial disappointment becomes a breach claim.
[ ] Agree a single channel for sponsor complaints during the event.
- Trap. Sponsors calling three different people receive three different answers.
[ ] Agree that the post-event review will be shared.

Phase 7. Venue and perimeter

[ ] [Gate] Secure control of all signage inside the venue, including permanent sponsor signage that must be covered or removed.
[ ] Secure control of exterior and immediate perimeter signage.
[ ] Secure control of vending and distribution within the venue footprint.
[ ] Secure control of concession branding.
- Trap. A stadium with naming rights and long-term category sponsors hosting an event with different sponsors in the same categories. Resolve this in the venue agreement, not on the day.
[ ] Secure the right to remove persons and materials.
[ ] Secure rights over airspace where obtainable, for aerial advertising and drones.
[ ] Secure control of the venue's own social channels during the event window.
[ ] Obtain a schedule of what the venue has already committed to its own sponsors, and how conflicts resolve.
[ ] [Gate] Take options on perimeter, transit, and building-wrap media at least a year out.
- Why. Media owners sell to whoever books first, and a competitor planning an ambush books six months ahead.
[ ] Check whether temporary flight restrictions will cover banner-towing, which is regulated for safety reasons independent of advertising.

Phase 8. Clean zone

[ ] [Gate] Negotiate the clean zone commitment in the host city agreement at bid stage.
- Why. An organiser without hosting leverage will not obtain one, and it is not an operational detail to be raised later. See clean zone ordinances for major events.
[ ] Specify the geographic perimeter and the time window.
[ ] Specify restrictions on temporary signage, commercial distribution, and unlicensed vending.
[ ] Specify an exemption process the organiser participates in.
[ ] [Gate] Secure enforcement resourcing, because an unenforced ordinance is decorative.
[ ] Confirm the drafting is proportionate, since an overbroad ordinance restricting non-commercial speech invites challenge and is struck.
[ ] Confirm the treatment of pre-existing permanent signage, which is generally grandfathered.
[ ] Brief sponsors on the limits: temporary, bounded, and ineffective against ambush run just outside the perimeter or entirely in media.
[ ] Map the perimeter against where ambush actually occurred at the last edition.

Phase 9. Ticket and registration terms

[ ] Prohibit commercial activity, promotion, and distribution of promotional material.
[ ] Prohibit entry with branded items in commercial quantities.
[ ] Prohibit unauthorised recording and re-transmission.
- Why. 17 U.S.C. § 106 reaches the broadcast production, not an attendee's own recording of facts, so in-venue streaming is controlled by contract.
[ ] License the attendee's likeness for broadcast and promotional use.
[ ] Reserve the right to eject, confiscate, and refuse re-entry without refund.
[ ] Restrict resale and use in promotions.
[ ] Bind transferees, so a corporate buyer cannot circumvent the terms.
[ ] [Gate] Confirm formation: terms presented at purchase and referenced on the ticket.
- Trap. Terms that were never properly presented bind nobody, and the whole in-venue strategy rests on them.
[ ] For conferences, add restrictions on off-site activity marketed to registrants.
[ ] For trade shows, add exhibitor obligations covering off-site hospitality timed to the event.

Phase 10. Participant agreements

[ ] Specify what marks may be displayed during competition, on equipment, and in the mixed zone.
[ ] Specify media obligations, including press conferences and backdrop appearances.
[ ] Specify image and footage rights for the organiser.
[ ] [Gate] Include a personal-sponsor window restricting campaigns by the participant's own sponsors during a defined period around the event.
- Why. Athlete ambush is lawful and the participant agreement is the only mechanism that addresses it.
- Trap. Expecting the concession free. Personal sponsorships are the athlete's income; budget for it in appearance fees.
[ ] Require the participant to procure that each personal sponsor is bound.
[ ] Address digital replicas and synthetic reproduction of likeness or voice expressly. See Synthetic You.
[ ] Negotiate with representatives and player associations rather than presenting terms.
[ ] Confirm the agreement is signed before entries close.
[ ] Extend equivalent obligations to teams, coaches, and support staff.

Phase 11. Athlete rights

[ ] Confirm the applicable right of publicity, which is state law and varies in scope, duration, and post-mortem treatment. See state right of publicity statutes.
[ ] Confirm the licence obtained in the participant agreement covers each intended use.
[ ] Note that the right is assignable, per Haelan Laboratories v. Topps Chewing Gum, which is what makes the endorsement market possible.
[ ] Note that broadcasting a performer's entire act without consent is not protected, per Zacchini v. Scripps-Howard Broadcasting.
[ ] Note that expressive depictions may be protected against a publicity claim, per ETW v. Jireh Publishing.
[ ] [Gate] Do not sell names and statistics as exclusive.
- Why. C.B.C. Distribution v. Major League Baseball Advanced Media and National Basketball Association v. Motorola put the facts of competition beyond anyone's control.
[ ] For collegiate participants, confirm the applicable state statute and institutional policy on name, image, and likeness, and treat them as commercial parties. See National Collegiate Athletic Association v. Alston.
[ ] Confirm minors' agreements are executed by a parent or guardian and comply with local requirements.
[ ] Confirm what happens to image rights after the event and for archive use.

Phase 12. Broadcast and digital

[ ] Confirm the organiser owns the audiovisual work produced, protectable under 17 U.S.C. § 102 and fixed simultaneously with transmission as 17 U.S.C. § 101 permits.
[ ] Confirm it does not own the underlying event, and that scores and results are free.
[ ] Specify advertising restrictions within the broadcast, and their limits given the broadcaster's own advertiser commitments.
- Trap. Promising a sponsor broadcast adjacency exclusivity the broadcaster cannot deliver.
[ ] Specify on-screen graphics, virtual signage, and digitally inserted advertising, allocating control between organiser, venue, and broadcaster.
[ ] Specify clip and highlight licensing terms.
[ ] Specify archive rights, which outlive the event by decades.
[ ] Specify territorial limits and sub-licensing.
[ ] Include anti-piracy cooperation obligations, and establish platform relationships before the event.
[ ] Confirm dynamic blocking availability in the relevant jurisdictions.
[ ] Confirm what digital and social inventory the organiser can actually grant.
[ ] Confirm data and audience rights are consistent with privacy obligations.

Phase 13. Counterfeit programme

[ ] [Gate] Complete customs recordation in host, manufacturing, and transit markets by six months out.
[ ] Supply product identification guides to enforcement agencies, and update them when packaging or features change.
[ ] Enrol in marketplace brand registries by three months out.
- Why. Listing volume peaks in the fortnight before the event and disappears afterwards; a programme configured during the event has missed it.
[ ] Identify warehouse-scale operations in advance and prepare ex parte seizure applications under 15 U.S.C. § 1116.
[ ] Assess statutory damages exposure under 15 U.S.C. § 1117, including the enhanced range for wilfulness.
[ ] Coordinate street enforcement with local authorities under municipal vending and permitting controls.
[ ] Implement authentication features on official merchandise, serialised where volume justifies it.
[ ] Prepare default judgment templates for unreachable sellers.
[ ] Record outcomes, because counterfeit recoveries frequently fund the wider programme.

Phase 14. Licensee control

[ ] Include audit rights over production quantities in every merchandise licence.
[ ] Require lot accounting and traceability.
[ ] [Gate] Require certified destruction of overruns and surplus.
- Why. Genuine goods produced beyond the order and sold outside the channel present identically to counterfeits and are frequently misdiagnosed as them.
[ ] Restrict subcontracting, with flow-down obligations.
[ ] Specify approved distribution channels and prohibit sales outside them.
[ ] Specify quality standards and approval of samples.
[ ] Specify what happens to unsold inventory at the end of the term.
[ ] Specify tooling ownership and return.
[ ] Audit at least one licensee per cycle rather than none.

Phase 15. Monitoring setup

[ ] [Gate] Configure monitoring one month out, not during the event.
[ ] Cover perimeter media, transit sites, and building wraps.
[ ] Cover competitor advertising in host and broadcast markets.
[ ] Cover social keyword and image searches, including the event hashtags and mark variants.
[ ] Cover marketplace listings for merchandise.
[ ] Cover broadcast adjacency.
[ ] [Gate] Name an approver with authority to authorise a letter without a committee.
- Trap. A letter waiting three days for sign-off, by which time the event has ended.
[ ] Pre-clear letter templates for the recurring categories: mark use, false designation, ticket terms breach, venue removal, platform report.
[ ] Circulate the triage rule to the on-site team so they apply it rather than escalating everything.
[ ] Establish contacts in advance: platforms, media owners, the broadcaster, retailers, and municipal enforcement.
[ ] Set a single channel for sponsor complaints.
[ ] Log everything with times, because response time is the operational metric.

Phase 16. Enforcement triage

[ ] [Gate] Answer three questions before responding: what was used, what was represented, and where did it happen?
[ ] Event marks used. Send, quickly and firmly.
[ ] Sponsorship claimed or strongly implied. Assess the specific representation under 15 U.S.C. § 1125, consider survey evidence, and send narrowly on that representation alone.
[ ] Neither, but inside the venue, the clean zone, the broadcast, or a contracted relationship. Use the contractual or municipal route.
[ ] None of the above. No claim. Record it, brief the sponsor, and treat it as commercial and communications work.
[ ] [Gate] Never send a letter asserting rights that do not exist.
- Why. Ambushers publish them, and the public refusal outperforms the ambush.
[ ] Prefer faster remedies: platform reporting, venue removal, media owner contact, broadcaster intervention, retailer contact, municipal enforcement.
[ ] Assess proportionality, because enforcement at an event is public — an ejection over a branded t-shirt reads badly and serves no sponsor's interest.
[ ] Enforce usage guidelines against sponsors as well as outsiders, since the organiser's own sponsors are the most common source of designation misuse.
[ ] Prepare counter-programming, since prepared sponsor activation is the most effective answer to lawful ambush.

Phase 17. Social layer

[ ] Confirm that hashtags are not owned, and assert only where a registered mark is reproduced in commerce.
[ ] Accept that timed and congratulatory posting is lawful and unstoppable.
[ ] Check competition and giveaway entry terms, which is where a false designation usually appears and where a lawful campaign becomes actionable.
[ ] Enrol in platform brand protection programmes before the event.
[ ] [Gate] Do not enforce against fan content.
- Why. It is a communications failure no legal position justifies.
[ ] Route athlete content issues to the participant agreement, not to a letter to the brand.
[ ] Prepare the sponsor's own content to occupy the space at key moments.
[ ] Monitor for accounts impersonating the event or claiming official status, which is the clean case.

Phase 18. Sponsor-side diligence

[ ] Establish what is being bought and, explicitly, what is not.
[ ] Ask whether the organiser controls the venue perimeter, and what the venue has committed to its own sponsors.
[ ] Ask whether the organiser or the broadcaster controls advertising adjacency.
[ ] Ask whether there is a clean zone and what it covers.
[ ] Ask what the participant agreements say about personal sponsor windows.
[ ] Ask what marks are registered, in which classes and territories.
[ ] Ask what ambush occurred at the last edition and what the organiser did about it.
[ ] [Gate] Negotiate protection obligations with a remedy attached.
[ ] Negotiate the category definition with adjacency, portfolio, and acquisition treatment.
[ ] Buy the surrounding inventory where the organiser cannot deliver it.
[ ] Secure first refusal on renewal, which is cheapest at first signature.
[ ] Plan activation, because visible consistent presence is the most reliable protection available.

Phase 19. The calendar

[ ] Twenty-four months out, or at bid. Clean zone commitment in the host city agreement; venue perimeter control in the venue agreement.
[ ] Eighteen months out. Mark applications filed on intent to use in home, host, and broadcast markets; base marks confirmed alive and in use.
[ ] Twelve months out. Category definitions drafted before sponsor negotiations open; perimeter and transit media options taken.
[ ] Nine months out. Sponsor agreements executed with ambush obligations and remedies; broadcast agreement addressing adjacency, virtual signage, and archive rights.
[ ] Six months out. Customs recordation completed; licensee agreements with overrun controls; participant agreements circulated with personal-sponsor windows.
[ ] Three months out. Ticket, registration, and exhibitor terms finalised and properly presented; marketplace registry enrolment; monitoring configured.
[ ] One month out. Letter templates pre-cleared; approver named; triage rule circulated; identification guides delivered to agencies; sponsor activation plans confirmed.
[ ] During. Monitor, triage, act within hours, record everything.
[ ] Within one month after. Post-event review completed while the people who ran it are available.
[ ] Between editions. Base marks maintained, registrations renewed, venue and city relationships kept warm.

Phase 20. Post-event review

[ ] Record every identified ambush, categorised: mark use, false designation, thematic, proximity, distribution, athlete, ticket, social, counterfeit.
[ ] Record what was done — letters, platform reports, removals, municipal enforcement — with outcomes and dates.
[ ] [Gate] Record what could not be done, and why.
- Why. This is the most useful section, because it identifies the inventory to buy and the terms to negotiate next time.
[ ] Record sponsor complaints and whether each had a legal basis.
[ ] Record median hours from identification to action.
[ ] Assess whether the venue agreement, ticket terms, participant agreements, and clean zone perimeter covered what happened.
[ ] Assess whether the marks that mattered were registered in the right classes and territories.
[ ] Assess counterfeit seizures and recoveries against programme cost.
[ ] Feed the findings into the next cycle's calendar and sponsor negotiations.
[ ] Share it with sponsors as agreed, since it is the renewal negotiating document for both sides.

Phase 21. If you can only do four things

[ ] File the marks and keep the base marks alive. Cheap, and their absence is the failure that recurs between editions.
[ ] Control the venue and the perimeter. The strongest protection available, and it is a contract rather than a claim.
[ ] Present the ticket terms properly. The whole in-venue strategy rests on formation.
[ ] Buy the surrounding media. It prevents more ambush than every letter ever sent.

Phase 23. Scaling to the event

[ ] Major international competition. Bid leverage produces a clean zone and sometimes host country legislation. Portfolio across dozens of markets, customs recordation everywhere, a monitoring operation, on-site enforcement teams, and established platform and media owner relationships. The distinctive risk is scale.
[ ] National league or tour. Base marks matter more than any edition's composite; venue relationships are long-term; participant agreements are collective and negotiated with player associations, making personal-sponsor windows a bargaining issue. Broadcast is both the principal asset and the principal exposure.
[ ] Single major event without hosting leverage. No clean zone, limited perimeter control, sponsors expecting both. Register properly, control the venue and tickets, buy the available perimeter media, set expectations at negotiation, and monitor with a small team.
[ ] Trade show or conference. The ambush is exhibitors and non-exhibitors working the attendee list — off-site hospitality, materials in the queue, parallel events marketed to registrants. Registration terms, exhibitor agreements, and corridor control are the whole answer.
[ ] Regional or community event. Category precision matters more, not less, because sponsors are direct competitors in a narrow field. Monitoring is a person with a phone. Enforcement is a conversation, and it works because the parties meet again next year.
[ ] [Gate] Confirm the programme matches the event's actual leverage. Promising a sponsor clean-zone-level protection at an event with none is how a commercial disappointment becomes a claim.

Phase 24. Working with other parties

[ ] Host city. Engage municipal counsel and the events office at bid stage. Ask what perimeter is achievable, what enforcement resource comes with it, and how exemptions work.
[ ] Venue. Obtain the schedule of existing sponsor commitments early, because a venue with naming rights and category sponsors is the most common source of on-the-day disputes.
[ ] Broadcaster. Establish what it can commit given its advertiser relationships, before a sponsor is promised adjacency exclusivity.
[ ] Athlete representatives and player associations. Negotiate personal-sponsor windows rather than presenting them, and budget for the concession.
[ ] Media owners. Book early; many have their own terms about misleading advertising that can be invoked faster than any claim.
[ ] Platforms. Enrol and establish a contact before the event, or join a queue during it.
[ ] Enforcement agencies. Supply identification guides and a named contact; their effectiveness depends entirely on preparation.
[ ] Sponsors. Brief them before signature on what is achievable, and give them one complaint channel during the event.

Phase 25. The one-page position

Event — [name], [edition], [dates], [host]. Marks: composite filed [date, classes, territories], registered [numbers]; name [status, acquired distinctiveness argument prepared yes/no]; mascot and trophy [status]; edition composite [status]; base marks alive and in use [confirmed date]; watch service [active from]; customs recordations [markets, dates]. Designations: [list]; registered [yes/no]; usage guidelines issued [date]; conflicts across categories [none / description]. Sponsors: [N]; categories defined by product and claim [confirmed]; adjacency clauses [present/absent]; portfolio clauses [present/absent]; acquisition clauses [present/absent]; ambush obligations with remedy [present/absent]; complaint channel [named]. Venue: signage control [scope]; perimeter control [scope]; vending and distribution control [scope]; existing venue sponsor commitments [schedule obtained date]; airspace [obtained / not]; removal rights [confirmed]. Perimeter media: sites identified [N]; secured or under first refusal [N]; open [N]. Clean zone: [none / obtained]; perimeter [description]; window [dates]; enforcement resource [description]; exemption process [organiser participates yes/no]. Tickets: terms finalised [date]; formation confirmed [date, method]; prohibitions [commercial activity / distribution / recording / resale]; transferee binding [confirmed]. Participants: agreements signed before entry close [N of N]; personal-sponsor window [days before / after]; digital replica terms [present/absent]; negotiated with [representatives / association]. Broadcast: adjacency restrictions [scope, deliverable by broadcaster yes/no]; virtual signage allocation [description]; clip licensing [terms]; archive rights [holder, duration]; anti-piracy cooperation [present/absent]. Counterfeits: recordations complete [date]; identification guides delivered [date]; marketplace enrolments [date]; seizure applications prepared [N]; licensee overrun controls [present/absent]. Monitoring: configured [date]; scope [perimeter / transit / social / marketplace / broadcast]; approver [name]; pre-cleared templates [N]; triage rule circulated [date]. During event: ambush identified [N]; mark use [N]; false designation [N]; lawful thematic [N]; actions taken [N]; median hours to action [figure]; letters sent [N]; claims declined for lack of rights [N]; sponsor complaints [N, with basis N]. Post-event review completed [date]; shared with sponsors [date]. Actions for next edition: [list].

Phase 26. What this costs

[ ] Mark filings are the cheapest item and their absence is the most common failure between editions.
[ ] Base mark maintenance costs renewal fees and a docket entry.
[ ] Perimeter media options are the largest discretionary line and prevent more ambush than every other measure combined.
[ ] The clean zone costs negotiating leverage rather than money, and is unavailable without it.
[ ] Ticket and participant terms cost drafting time once and are reused each edition.
[ ] The personal-sponsor window costs real money in appearance fees, and there is no cheaper route to it.
[ ] Customs recordation costs very little and works continuously.
[ ] Monitoring at a small event is a person with a phone; at a large one it is an operation.
[ ] Counterfeit recoveries frequently fund the wider programme.
[ ] The asymmetry. Every item is cheap at its point in the calendar and unavailable afterwards, because the event ends. That is the whole argument for running this against dates rather than events.

Phase 27. Between editions

[ ] Maintain the base marks in use, not merely on the register.
[ ] Renew registrations and file declarations on the docket.
[ ] Review watch results for squatter filings in host markets.
[ ] Keep the venue and host city relationships warm, because clean zone leverage is relationship-dependent.
[ ] Refresh customs recordations and identification guides.
[ ] Review the previous post-event findings against the next edition's plan.
[ ] Re-examine category definitions against sponsors' changed businesses.
[ ] Confirm participant agreement templates reflect current practice on digital replicas and personal-sponsor windows.

Phase 22. Metrics

[ ] Marks registered in home, host, and broadcast markets before announcement.
[ ] Base marks maintained between editions. Any lapse is a programme failure.
[ ] Category definitions containing adjacency, portfolio, and acquisition clauses.
[ ] Sponsor agreements containing ambush obligations with a remedy attached.
[ ] Perimeter and transit inventory secured or under first refusal, as a percentage of identified sites.
[ ] Clean zone perimeter measured against where ambush actually occurred.
[ ] Ticket terms confirmed properly formed.
[ ] Participant agreements containing a personal-sponsor window.
[ ] Customs recordations completed by six months out.
[ ] Marketplace enrolments completed by three months out.
[ ] Median hours from identification to action during the event.
[ ] Letters sent against claims declined for lack of rights.
[ ] Sponsor complaints, and the proportion with a legal basis.
[ ] The one that matters. Whether any sponsor renewed at a lower value citing ambush at the previous edition.

Outcome. The billboards were lawful and there was never a claim. What changed was everything scheduled around them. Perimeter and transit media went under first refusal a year out, and the sponsor bought it. The clean zone, unavailable for this event, was written into the next host city agreement at bid. Category definitions were rewritten by product and claim with adjacency, portfolio, and acquisition clauses, ending two sponsor-versus-sponsor disputes that had been more expensive than the ambush. The ticket terms were re-presented at purchase after a formation review found them referenced only in a footer. Participant agreements gained a personal-sponsor window, negotiated with representatives and paid for in appearance fees. Customs recordation went in at six months and marketplace enrolment at three, and seizures the following edition covered the programme's cost. Monitoring was configured a month out with a named approver and five pre-cleared templates, and median response time fell from three days to four hours. Of eleven ambush attempts identified at the next edition, three used marks or claimed association and were resolved within a day each; eight were lawful and were answered with activation rather than letters. No letter was published, and no sponsor renewed at a lower value.

The five things people get wrong

One. They expect trademark law to stop ambush. Most ambush uses no marks and claims no sponsorship, and it is lawful. 15 U.S.C. § 1125 reaches a representation about the relationship, not an association created by proximity and theme.

Two. They leave the perimeter media on the market. Billboards and transit sites around a venue are bought in the ordinary market, six months ahead, by whoever asks. An organiser or sponsor that does not book them has funded the ambush it later complains about.

Three. They define sponsor categories by industry label. "Beverages" is not a category. Imprecision produces disputes between sponsors, which is worse than any outside conduct.

Four. They have no personal-sponsor window in the participant agreement. An athlete's own sponsor running a campaign timed to the event is lawful, and the participant agreement is the only mechanism that addresses it. Expect to pay for the concession.

Five. They build the response during the event. Monitoring, letter templates, a named approver, customs recordation, and marketplace enrolment all have to exist beforehand, because the event ends before anything started on the day matures.
