Investor Due Diligence on Startup Patents: Provisional Quality, Deadlines, and Continuation Strategy
The script advises investors how to evaluate startups that claim patent filings by checking whether applications are provisional or non-provisional, ensuring provisionals contain substantial technical detail, and confirming the company has a docket and someone responsible for converting to a non-provisional within one year. It warns that missing the deadline—especially after sales or public use—can create prior art that destroys patent rights, leaving only the possibility of patenting a later “version two.” It explains why detailed provisionals are valuable (e.g., drug companies use them to effectively extend patent life to 21 years) and emphasizes strong patents for business exclusivity. The discussion then covers how companies protect evolving software through foundational patents kept alive via continuation applications, plus filing new patents around upcoming releases by identifying market-facing features and their technical implementation.00:00 Investor Due Diligence on Startup Patents 03:22 Patents for Iterations05:45 Feature-Driven IP Strategy06:48 Wrap Up and Takeaways
