Why Forum Matters More in Patent Litigation
In most civil litigation, venue selection is an important but not dominant strategic consideration. In patent litigation, forum selection has historically been outcome-determinative in ways that are exceptional even by litigation standards. The rise and fall of the Eastern District of Texas, the emergence of the Western District of Texas under Judge Albright, and the consistent strength of the District of Delaware have made forum selection a primary strategic decision in every major patent case.
The Current Patent Litigation Forum Landscape
Patent venue law changed significantly with TC Heartland LLC v. Kraft Foods (2017), limiting venue to where the defendant is incorporated or has a regular place of business and has been served. This reduced but did not eliminate forum shopping — Delaware remains the default forum for cases against corporations incorporated there, and the Western District of Texas has captured substantial docket through a combination of an active patent judge and relatively short times to trial.
Current data on major patent venues:
- District of Delaware: Large docket volume, sophisticated bench, historically balanced outcomes between plaintiffs and defendants, slower to trial than Texas venues
- Western District of Texas (Waco Division): Very fast to trial, high patent holder win rates under Judge Albright's management, though venue transfers to more convenient forums have increased
- Northern District of California: Tech-sophisticated judges, more defendant-favorable on validity challenges, significant San Jose/San Francisco division differences
- District of New Jersey: Pharmaceutical patent litigation hub (Hatch-Waxman), sophisticated bench on biologics and small molecule issues
PTAB vs. District Court: The Parallel Track Decision
The America Invents Act created inter partes review (IPR) and post-grant review (PGR) at the Patent Trial and Appeal Board — providing a parallel, faster, cheaper route to challenge patent validity compared to district court.
IPR institution rates have declined since the Supreme Court's SAS Institute decision requiring the PTAB to address all challenged claims if it institutes at all. Current data shows institution rates around 60-65% for IPR petitions, with petitioners winning (resulting in cancellation or disclaimer of all challenged claims) in roughly 60-70% of instituted proceedings.
The strategic calculus involves multiple considerations: IPR estoppel (preventing litigation of grounds raised or reasonably could have been raised in IPR), district court stay likelihood, timing relative to the case schedule, and whether the invalidity grounds are stronger under BRI (IPR) or Phillips claim construction (district court).
Damages Calculation: What's Working
Patent damages calculation has been the subject of significant Federal Circuit scrutiny over the past decade. The EMVR (entire market value rule) restrictions, apportionment requirements, and challenges to entire categories of royalty benchmarks have made damages presentations more complex and more vulnerable to expert exclusion challenges.
Current data on what damages approaches are surviving Daubert challenges and resulting in jury awards suggests that:
- Bottom-up royalty rate analyses with strong technical decomposition of the patented feature's contribution to the product perform better than top-down approaches
- Comparable license benchmarks remain the strongest royalty rate evidence when the comparable licenses are genuinely comparable
- Broad entire market value rule claims remain vulnerable and courts continue to require careful apportionment to the patented technology specifically
Using Patent Analytics in Practice
AI-powered case analytics applied to patent litigation can surface: how often a specific judge has stayed litigation pending IPR (important for the IPR filing decision), what damages approaches have succeeded or failed before your assigned judge, and how similar patents have fared in validity challenges. This intelligence, applied systematically, informs strategic decisions that can be worth millions of dollars in litigation.
