Inside Patent Prosecution: Office Actions, Restrictions, Continuations, and the Path to Allowance
By Casey Scott McKay ·
Patent prosecution looks like correspondence and is actually a structured negotiation with rules, clocks, and a permanent record. This article explains what happens between filing and issuance: how applications are classified and queued, what an office action actually contains, why the first one is almost always a rejection and what that means, how restriction requirements split an application and why the divisional matters, what final really means, and when a continuation is worth more than the patent it comes from. It covers the mechanics practitioners live by - deadlines, extensions, interviews, requests for continued examination, appeals - and the strategic decisions those mechanics enable. It closes with the point most inventors never hear: everything said during prosecution becomes evidence, and the file wrapper is read aloud in every dispute that follows.
