IPR estoppel: the trade-off behind the cheapest invalidity tool
File your strongest art, file it well — or don't file at all if your strongest grounds aren't patents and publications. Estoppel is what makes IPR powerful for the system and dangerous for the defendant who underprepares.
Alice Corp. v. CLS Bank International (2014)
Bolting 'on a computer' onto an abstract business process doesn't make it patentable. Most software and business-method patents that look like 'doing X on a computer' don't survive when seriously challenged under Alice.
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.
Patent term and expiration
Patents don't last forever. They don't even reliably last 20 years. The expiration date that actually matters depends on the earliest filing date, the maintenance schedule, and any USPTO or FDA delays the patent owner can claim back.
