Changes in Patent Language to Ensure Eligibility Under Alice

When a rule becomes a target, it ceases to be a good rule.  In the three years since the Supreme Court issued its opinion in Alice, there have been positive changes to patent applications, but there remains a long-term risk that patent practitioners will use tricks to beat the Alice test.  Here, we focus on the changes to patent applications by drafters, as well as changes to patent applications that have issued since Alice… Previous analyses have reported that patent specification length has been increasing since long before 2010. As shown in Figure 3, from 2010 to 2013, the average patent application length was approximately 12,417 words. However, from 2015 and 2017, the average patent application length increased to over 14,700 words… Alice appears to have resulted in positive developments, such as narrowing the scope of claims and increasing disclosure of technical benefits of inventions in the specification.

PTAB due process violations raised in brief to Federal Circuit

On September 22nd, a reply brief for appellant Cascades Projection LLC was filed to the U.S. Court of Appeals for the Federal Circuit in a case over the validity of patents covering projector technologies which were invented by Gene Dolgoff, the creator of the Star Trek Holodeck. The appeal against Japanese tech conglomerates Epson and Sony asks the Federal Circuit to decide whether the Patent Trial and Appeal Board (PTAB) erred in invalidating patent claims held by Cascades Projection and whether the PTAB acted in a manner which violated Cascade Projection’s right to due process under the U.S. Constitution.

Beware of Conditional Limitations when Drafting Patent Claims

Buried in the claim language, conditional limitations may be a vulnerability in an otherwise valuable claim. A conditional limitation is a claim feature that depends on a certain condition being present. For example, when or if condition X is present, feature Y is implemented or has effect. Without condition X, feature Y may be dormant or have no effect. Patent owners should be cognizant of possible conditional limitations implications because conditional limitations may affect claim validity and infringement as discussed below in the context of recent U.S. Patent Office and Federal Circuit cases. In Ex Parte Schulhauser, the Patent Trial and Appeal Board (“the Board”) held certain claims as unpatentable based on conditional limitations.

Lex Machina commercial litigation report shows that one-fifth of commercial cases include IP claims

The total number of intellectual property claims included in all commercial cases is higher than the figure of 11,643 commercial cases including at least one IP claim. “It turns out to be incredibly hard to build a Venn diagram that reflects the types of IP claims included in these commercial cases,” said Brian Howard, Lex Machina data scientist and the author of the commercial litigation report. “It turns out to be its own mini-Venn diagram within a Venn diagram, some of the cases are patent and trademark and commercial, so there’s overlap within that IP circle.” Of the different types of intellectual property claims which are included in commercial litigation, trademark claims are by far the most common, occurring in a total of 8,277 commercial cases; that’s 15 percent of all commercial cases filed since 2009. Copyright claims were brought in a total of 3,260 commercial cases filed since 2009, a total representing about 6 percent of all commercial cases. Patent claims were brought in 2,219 commercial cases, or only about 4 percent of the total.
