Bilski v. Kappos (2010)
Machine-or-transformation isn't the only § 101 test, business-method patents survived as a category, and the specific Bilski hedging method was unpatentable. The trio of Bilski, Mayo, and Alice gave defendants the modern § 101 motion.
AI prior art search tools: a 2026 buyer's guide for defendants
AI doesn't replace a patent attorney's judgment. It does replace the search step that used to cost $20,000 and take three weeks.
The first 30 days after a patent infringement complaint
Most defendants spend the first 30 days reacting. The defendants who do well spend it sequencing — because every move you make in month one shapes the budget, leverage, and exit options for the next two years.
The patent litigation lifecycle
Most patent cases never reach trial. A defendant who understands the lifecycle makes better decisions about when to fight, when to settle, and when to invest in IPR — instead of overspending on whatever phase they happen to be in.
How patent trolls operate (and why the business model works)
A junk patent generates settlement income exactly the same way as a strong one, because nobody pays $1M to test a $200k demand. The mechanics matter because the failure modes — what makes assertion campaigns expensive or risky for the troll — are exactly where defendants find leverage.
