Recent court rumblings about a narrow scope of IPR estoppel

An Inter Partes Review (IPR) is an important tool for companies that face frequent patent infringement challenges. An IPR is essentially a mini-litigation focusing solely on patent validity conducted before a panel of administrative patent judges sitting in the Patent Trial and Appeal board (PTAB). Once an IPR is initiated, a decision on validity is issued within one year. The narrow focus, fast timing, and lower cost of an IPR, along with certain legal advantages that make proving invalidity easier in an IPR than in a district court, make it an attractive alternative to district court litigation when good invalidity arguments are available.
