Patent owners must modify their strategies during prosecution to make their patents and portfolios less susceptible to post grant challenges. This strategy must take into account the cost of filing a petition by a challenger. Patent owners must obtain enough claims and enough patents to make it extremely expensive for a challenger to go down the path toward an administrative patent trial where the deck is stacked against the patentee. This will require patent owners to obtain patent claims with numerous dependent claims that cover as many variations as possible, but also to ensure that the dependent claims build on one another little by little so as to create a claim set that refers back to as many previous claims as possible. Such a claim mosaic will raise the filing fee that must be paid to institute a post grant challenge.

The administrative trial proceedings created by the AIA are: (1) Inter partes review; (2) post-grant review; (3) covered business method patents review; and (4) derivation proceedings. To bring these new proceedings into being, the USPTO issued a number of final rules and a trial practice guide in August and September of 2012. It is now time for the USPTO to take a step back and take account of these new proceedings, aided by public input. This is not an unexpected occurrence. Many will recall that during the rule making phase the USPTO held roundtable discussions in a number of cities across the country. During this timeframe the USPTO committed to revisiting the rules and practice guide once the Board and public had operated under the rules and practice guide for some unspecified period of time and had gained experience with the new administrative trial proceedings. With nearly two years of practical experience with these new proceedings, the time has now come for the USPTO to revisit and quite possibly revise the rules.

What seems to be happening is that the PTAB is literally applying KSR v. Teleflex in a way that many initially feared it would be applied, but in a way it has never been interpreted by the Federal Circuit. Under a literal reading of KSR nothing is patent eligible… If you are a defendant in a patent infringement litigation and you haven’t filed an inter partes review, what are you waiting for? The Patent Office giveth with the examiners allowance and taketh away with a PTAB decision. As long as the PTAB is killing patents can you blame defendants and their lawyers? It would be practically malpractice for a defense attorney in a patent infringement case to fail to recommend seriously considering inter partes review.

The Board cancelled 95.2% of all claims for which trial was instituted, and cancelled 82.9% of all claims that were initially challenged by the petitioner… These bleak statistics have lead Federal Circuit Chief Judge Randall Rader to at the AIPLA annual meeting in October 2013 call the PTAB “death squads killing property rights.” Then again on Friday, March 21, 2014, at a conference hosted by the George Mason University School of Law, Chief Judge Rader said he was “troubled” by the many differences between proceedings at the PTAB and in the district courts, particularly pointing to the disparities in the treatment of the same evidence concerning the same claims. Rader mentioned that his recent comments about the Board being a “death squad” for patents in contested proceedings may be more accurate than some originally thought, considering the dismal track record for survivability of challenged claims in the first wave of final written decisions.

KUNIN: ”But what is the one thing that can be a break the bank issue? What if the patent owner asserts eight patents against you in a litigation. Can you pick and choose which are the best patents among the eight to challenge? Or are you going to have to file and pay for eight IPRs? At what particular point does it actually become a financial burden for you to go after every asserted patent against you in that litigation in separate IPRs? Either you can try to strategically determine which are the patents which are most harmful to you and most vulnerable and go after them in IPRs, or try to go after all of them in IPRs. But if you go after all of them, you already explained how expensive it is, all right? So let’s assume for argument sake it’s a fairly complex proceeding and it’s costing $300,000 per IPR. So $300,000 times eight is the total cost. What’s the cost of the litigation in defending against all the asserted patents?”

All of this has to make you wonder whether any new patent legislation is necessary at this time. The House of Representatives has already passed new patent legislation that focuses on patent litigation and the perceived abuses. Reasonable minds can perhaps differ about whether the measures being discussed are good, bad or would do anything to address the manipulation of the judicial process by nefarious actors. The facts suggest, however, that patent litigation is declining and the administrative trials are increasing beyond expectations. This is significant because the administrative trials were created in order to offer defendants a better, cheaper avenue to challenge patents outside of litigation. So why not allow the reforms of the AIA time to work before once again tinkering with the patent laws and potentially upsetting the incentive to innovate?

When a patent is challenged by an IPR the challenge must be taken very seriously. Patent Office statistics for FY 2013 and FY 2014 through January 31, 2014, show that there have been a total of 361 decisions on IPR petitions, with 288 trials instituted. There have been 11 cases that have been joined and only 62 petitions denied, which corresponds with an 82.8% IPR petition grant rate. Having said this, the IPR grant rate during FY 2013 was 87.2%, while so far during FY 2014 the IPR grate rate has been 77.2%. This drop in IPR granting rate, while statistically relevant, should not lull patent owners into a false sense of security.

The “new normal” created by the PTAB has drastically altered the patent assertion landscape. Simply stated, when a patent owner is notified that a patent they own is being brought into a post grant proceeding the statistics, if not the gravity of the threat, suggest that it must be taken seriously immediately and competent representation must be obtained quickly. The burdens are different at the PTAB than they would be in the Federal District Court. Specifically, the PTAB will employ the standard USPTO technique of giving patent claims their broadest reasonable interpretation, which will make it easier for a claim to be determined to overlap with the prior art. Furthermore, in litigation patent claims are presumed valid and the defendant must prove by clear and convincing evidence that a claim is invalid for one or more reasons.

There is a time limit for preventing certain petitioners from initiating an IPR proceeding against a patent, and there is currently a petition for writ of mandamus to the Federal Circuit as to the scope of petitioners covered by the time bar. This issue arises because 35 U.S.C. §§ 315(b). 35 U.S.C. §§ 315(b) states that “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Unfortunately, the critical question regarding who exactly is covered by “privy of the petitioner” is not defined by the statute and is subject to great debate.

In part 1 of the interview we discussed why he choose McDermott, what it was like working for David Kappos and working with Federal Circuit Judge Ray Chen when he was Solicitor at the USPTO, and the appointment of Michelle Lee to be Deputy Director of the USPTO. In part 2 of the interview, which appears below, we discuss the new ethics rules adopted by the USPTO, the future of the USPTO, patent reform legislation, abusive patent litigation, and what the AIA was attempting to achieve relative to post grant patent challenges.

Nearly 44% of all patents on which petitions were filed against are patents being held by large entities. While this is a significant increase from the earliest days of IPR where nearly 90% of all patent challenges were waged against patent owned by small entities, small entities are still carrying a massively disproportionate load of the challenges particularly when one takes into account that at any time they comprise only 20% of all the patents in force… the increase in IPR’s against patents held by large entities appears to be almost entirely due to large entities challenging other large entities, with little increased participation by small entities in the IPR process being noted.

A recurring theme that can be traced through the patent reforms of the AIA to the current debate over patent litigation abuse is the issue of patent quality. A key component of the reported abuses is the assertion of allegedly invalid or overbroad patents, the very abuse for which AIA post-grant procedures were created, in order to improve patent quality. These matters of patent quality are being addressed by the changes made to the law by the Judiciary and by Congress in the AIA, which are only now beginning to be felt. It may well be premature to conclude that they are not doing the job. Take one major example, as a former Director of the USPTO in particular, I would support, as former Director Kappos did, giving the post-grant processes in the USPTO a chance to work.
