We welcome the arrival of Inter Partes Review (IPR), as of September 16, 2012, and Post Grant Review (PGR) as of March 16, 2012. It is open for debate as to whether the America Invents Act (AIA) is true patent reform, but what is absolutely clear is that the AIA has changed patent practice forever. Check back often for updates and blog entries, including a close watch on IPR filings and orders. In the meantime, enjoy the presentation found HERE of a timeline of events to occur in an inter partes review and post grant review. There are many, many details that simply cannot be displayed in such a format, as well as precedent to be watched at the Patent Office as the Patent Trial and Appeals Board (PTAB) begins to handle its first cases. But, this overview provides a fairly in-depth perspective on what patent owners and patent challengers can expect with these new proceedings. Happy Litigating at the Patent Office!
