Hulu v. Sound View: The PTAB Sets New Precedent on How to Prove a Reference Is a Printed Publication

Posted by Stuart Duncan Smith on May 19, 2020

Stuart Duncan Smith

Invalidity grounds in IPR that are not based on patents must be based on printed publications. But the nature of the evidence required at the time of institution to show that a non-patent reference is a printed publication has long been uncertain. The PTAB’s Precedential Opinion Panel (POP) in Hulu v. Sound View Innovations, IPR2018-01039 (Dec. 20, 2019), provided some clarity and left other issues for future PTAB panels to resolve.

Appearing before the Patent Trial and Appeal Board (PTAB) looks different as a result of COVID-19. The PTAB recently held a “Boardside Chat” to talk about how PTAB practice has changed. Here are some important changes practitioners should know regarding case management, CARES Act extensions and remote hearings at the PTAB.

Using Prosecution History in IPR: What You Say May Come Back to Help You

Posted by Stuart Duncan Smith on Mar 19, 2020

Stuart Duncan Smith

Prosecution history can be a minefield in patent cases, and IPR is no different. In the context of construing patent claims, much of the focus is often on whether the patent owner disclaimed particular subject matter from the scope of the claims. But two recent Federal Circuit decisions reviewing decisions in IPR illustrate that even absent disclaimer, patent owners may be able to save the challenged claims by pointing to their past statements during prosecution.

Non-Prior Art Evidence of the Prior Art? The Federal Circuit Says It May be Okay

Posted by Stuart Duncan Smith on Oct 29, 2018

Stuart Duncan Smith

Section 311(b) of the American Invents Act (“AIA”) provides that a petitioner may request cancellation of one or more claims of a patent “only on a ground that could be raised under section 102 and 103 and only on the basis of prior art consisting of patents or printed publications.” In light of this clear restriction on the evidence that can lead to the cancellation of a claim, one might reasonably assume that all of the petitioner’s evidence during that trial must be prior art. A recent decision from the Federal Circuit, however, shows that this assumption is not entirely correct. Rather, in some situations, the cancellation of a claim may turn on evidence that is not even prior art to the claim.

Who Bears the Burden in IPR? It Depends on the Argument

Posted by Stuart Duncan Smith on Oct 23, 2018

Stuart Duncan Smith

A hallmark of IPR proceedings is that the petitioner—not the patent owner—has the burden to prove that the challenged claims are unpatentable. This hallmark is statutory as section 316(e) of the American Invents Act (which created IPRs) provides that “the petitioner shall have the burden of proving a proposition of unpatentability.” And yet, a recent decision from the Federal Circuit confirms IPR nonetheless applies the traditional rule that can shift a burden to the patent owner to rebut the petitioner’s prima facie case of obviousness. Patent owners thus cannot blindly rely upon section 316(e) and, in certain circumstances, should consider submitting evidence to defend the claims.

SAS Institute: A Refresher on the “Other” IPR Case at the Supreme Court

Posted by Stuart Duncan Smith on Apr 22, 2018

Stuart Duncan Smith

As discussed in our prior post, the Supreme Court is poised to issue decisions in two cases about IPRs. The first case is Oil States Energy Services v. Greene’s Energy Group, which could eliminate IPRs and gut the PTAB role in reviewing issued patents. The second case, SAS Institute Inc. v. Iancu, could balloon the PTAB’s workload with new requirements. Although SAS has not garnered the limelight like Oil States, its potential to reshape IPRs is just as significant. The issue at stake—the propriety of the PTAB’s practice of instituting review on only some of the challenged claims rather than all of the challenged claims—does not threaten to eliminate IPRs entirely. SAS does, however, raise the possibility of a dramatic change in how IPRs occur, how they are reviewed in the courts, and how they affect litigation.

The End of Days for IPRs? A Refresher on Pending Supreme Court Decisions

Posted by Stuart Duncan Smith on Apr 20, 2018

Stuart Duncan Smith

The Supreme Court is poised to issue decisions in two IPR-related cases that some predict will end IPRs as we know them. One of the cases, Oil States Energy Services v. Greene's Energy Group, could eliminate IPRs and gut the PTAB’s role in reviewing issued patents. The other case, SAS Institute Inc. v. Iancu, could balloon the PTAB’s workload and could expose those requesting review of patents to greater risk if they fail to fully make their case.

As with all prophecies of the end (so far), prophesies of the end of IPRs could also be premature, as the Supreme Court could simply allow IPRs to continue in their current form. Read on for a brief refresher on the context of Oil States, and stay tuned for a preview of SAS. We will also cover the decisions as they come down, so be sure to subscribe to get the latest news.

Legislation to Curtail Sovereign Immunity in IPR May Be On the Way

Posted by Stuart Duncan Smith on Nov 13, 2017

A Native American tribe’s recent deal to obtain several pharmaceutical patents and seek dismissal of pending IPRs on the basis of sovereign immunity has piqued the public’s interest in sovereign immunity to IPR. The same tribe also recently asserted several other patents against Microsoft and Amazon, and may assert sovereign immunity from IPR there too. Prompted by the tribe’s actions, a subcommittee of the House Judiciary Committee held a hearing on what Congress can and should do about it. Although much of the hearing focused on what many perceive as the problem of tribal sovereign immunity in IPR—not the use of sovereign immunity to IPR by state universities—many of the proposed reforms would also target state universities. Whether any of these reforms will be enacted remains to be seen, but there are reasons to doubt their constitutionality.

Shifting Seas in Aqua Products as the Federal Circuit Eases the Burden of Amendment in IPR

Posted by Stuart Duncan Smith on Oct 11, 2017

Stuart Duncan Smith

To many patent owners in IPR, the prospect of a patent-saving claim amendment is all but illusory. The Board grants few motions to amend, which is one reason that few patent owners even request amendment. That may change with the Federal Circuit’s en banc decision in Aqua Products, Inc. v. Matal, which eased the patent owner’s burden of justifying an amendment, and increased the petitioner’s burden of opposing an amendment. This change affects not only the procedure of IPRs, which must now take into account the shifted burden, but also the strategy of IPRs.

ITC v. PTAB: Is Winning in IPR Enough to Avoid an ITC Exclusion Order?

Posted by Stuart Duncan Smith on Aug 30, 2017

Stuart Duncan Smith

Parties accused of patent infringement often turn to IPRs to invalidate the asserted patents, and winning in an IPR can mean relief from whatever remedy would be imposed as a consequence of a finding of infringement. That strategy came under examination in a recent decision from the International Trade Commission (ITC), which declined to get rid of an exclusion order (i.e., an injunction) even after the PTAB found the infringed claims unpatentable. That does not mean, however, that the party found to infringe is without options.
