Simultaneous/Redundant Petitions Attacking Same Claims Questioned
The Patent Trial & Appeal Board’s (PTAB) new focus on institution equities of serial petition challenges was the most significant development of 2018. Since that time the Board has expanded its equitable focus beyond follow-on petitions and similarly situated defendants to consider parallel litigation timing.
This week, the Board tackled a new consideration. That is, whether it makes sense from a fairness perspective to give an IPR petitioner 5 bites at the same apple. I have been expecting this one.
