Our Experience

Case Study
Mintz protected clients’ patents related to the cholesterol drug Livalo®. Mintz defended against three IPRs filed by generic manufacturers that had filed Abbreviated New Drug Applications (ANDA) with the FDA and secured Patent Trial and Appeal Board denials of institution of the generic companies’ IPR petitions.
Case Study
Mintz’s work for ELM 3DS at the patent office enabled ELM to continue patent infringement litigation in federal court in Delaware. Mintz attorneys took over inter partes reviews (IPRs) challenging the validity of ELM’s patent claims after the IPRs were instituted.
Case Study
Mintz defended Israeli telecom company RAD Data Communications against a USPTO petition for inter partes review (IPR) that challenged a patent covering one of RAD’s core technologies. The Patent Trial and Appeal Board issued a rare ruling denying institution of the IPR.

Our Approach

The Patent Trial and Appeal Board (PTAB) has made it clear that it won’t simply rubber-stamp issued patents. The majority of patents challenged before the PTAB have had at least one claim invalidated through these IPR proceedings. If your patent is under threat, or you need to defend yourself from claims of infringement, we will leverage our best strategies for winning on the merits — and our knowledge of the technical ins and outs of the board’s complex procedures — to help you secure a victory.

​Proven IPR Success

We've helped our patent owner clients preserve litigation-quality claims at a pace nearly double the national average in cases with Final Written Decisions. That win statistic increases when denials of institution are included. Our team has won multiple appeals challenging PTAB decisions at the CAFC, including achieving the first full reversal by the CAFC of an adverse PTAB decision.
