The biggest PTAB milestones so far. Is a rule tweak next?

The almost two years of Patent Trial and Appeal Board proceedings have been a steep learning curve. Now it seems the USPTO may make some changes to proceedings to take those lessons into account


The cover story of Managing IP’s September issue, which has just been published online, assesses the state of play for the PTAB almost two years after the new inter partes review and covered business method proceedings became available on September 16 2012.

The special report is in three parts available to subscribers and trialliists: part one looks at the surprising popularity of the PTAB and how the Federal Circuit will react; part two looks at why PTAB proceedings are catching on among pharma companies; and part three looks at the lessons learned from proceedings so far.

After a cautious beginning, petitions at the PTAB have gone through the roof since the middle of last year. As the report reveals, the popularity of these proceedings has left some patent owners worried that some of their best IP assets are at risk.

Going through PTAB proceedings is certainly harder and more daunting for patent owners than it is for petitioners. The very first IPR decision out of the PTAB, Garmin v Cuozzo, made it clear that there would be very little chance for discovery. A common gripe among patent owners is also that it is nigh on impossible to be granted a motion to amend. Live testimony, too, is rare, despite a general expectation that it would be permitted.

There has been only one instance of an amendment and only one instance of live testimony. The one amendment – granted, perhaps ironically, by the government to the government – has also been viewed more as a settlement than an amendment because it was unopposed.

As my story makes clear, many patent owners feel like the goalposts have been shifted on them. While some observers are pleased that there is now a relatively quick and efficient process for knocking out patents that should not have been granted – and thus providing an effective weapon against patent trolls whose potency has yet to be appreciated in the wider world – it is possible to also feel some sympathy for patent owners. Claims that were drafted for a different time and a different forum now suddenly look at risk, especially if there is no chance for amending them.

Concerned patent owners will be heartened to hear, then, that experienced USPTO watchers are sure that changes will be made to proceedings to take their concerns into account. The USPTO is canvassing the market for feedback on 17 suggested potential areas for change. Written comments must be received by September 16.

As former USPTO director David Kappos told me for the story: “I am 100% confident they will make some changes from what they learned from the input they are getting. I wouldn’t be surprised if some adjustments were made in the areas of permitting claim amendment and discovery.”

Changes at the PTAB may be afoot, then.

Below are my picks for 10 of the biggest PTAB milestones so far. What do you think will be some of the biggest ones to look out for going forward?

We will publish the second installment of our in-depth look into the PTAB online next month. This will include interviews with in-house counsel, statistics on the PTAB’s timeliness on hearings and determinations, and analysis of institutions and the most common reasons for denial.
