Federal Circuit Reverses PTAB Invalidation of Wireless Network Patent in Apple Cases Involving APJ Clements

The Court of Appeals for the Federal Circuit recently issued a decision in DSS Technology Management v. Apple, which reversed an earlier decision by the Patent Trial and Appeal Board (PTAB) to invalidate patent claims covering a wireless communication networking technology. The majority opinion, authored by Judge Kathleen O’Malley, and with Judge Jimmie Reyna concurring, found that the PTAB did not sufficiently explain the conclusions reached in order to invalidate the patent claims based on obviousness.

The Court also explained that no such explanation could be gleaned from the case record. The majority opinion also determined that the PTAB misapplied common sense as it applies to making an obviousness determination, specifically misapplying the Federal Circuit’s 2016 decision in Arendi S.A.R.L. v. Apple Inc., 832 F.3d 1355 (2016), which was also authored by Judge O’Malley. As was the error in Arendi, the PTAB allowed its own common sense to supply a missing claim limitation leading to invalidation on obviousness grounds. Simply stated, that is not appropriate under a proper obviousness determination.

More to this Dispute

While this may seem like an ordinary, garden variety misapplication of the law of obviousness by the PTAB, there is more beneath the surface. In this case one of the Administrative Patent Judges (APJs) hearing the case at the United States Patent and Trademark Office (USPTO) was APJ Matt Clements, who previously represented Apple as a defense attorney in patent infringement matters prior to joining the board. Rather than recuse himself from hearing Apple matters, according to data we’ve retrieved from Lex Machina he has now been assigned to some 52 petitions filed by Apple, with Apple not surprisingly doing remarkably well in those petitions.

If this dispute were litigated in an Article III court and a federal judge had represented Apple, disqualification would be mandatory unless no other judge could hear the case, and then proceeding would require the parties to agree in writing outside the presence of the presiding judge. Such a conflict for a practicing attorney could never be resolved if there would be a direct conflict, and where a potential conflict would exist would require a client waiver.

It is astonishing that the Patent Trial and Appeal Board STILL does not have Rules of Conduct or any kind of Code of Judicial Ethics that applies to Administrative Patent Judges. This is inexcusable, period.

Is the presence of APJ Clements on the panel why there was a rather fundamental misapplication of the law of obviousness in this case? It is impossible to tell. It may just be a fundamental misapplication of the law of obviousness — a mistake. But we should have to ask that question. That is the entire reason to have ethics rules in the first place, so you never have to ask whether a relationship or circumstance lead to a particular outcome instead of the merits. The closeness of the relationship between Apple and Clements, and the reality that Clements participated in a final written decision that favored Apple and fundamentally misapplied the law of obviousness requires serious questions to be raised, particularly where the PTAB continues to ignore the problem of conflicts and lack of a Code of Judicial Ethics for APJs.

The Patent

The patent at issue in this case is U.S. Patent No. 6128290, titled Personal Data Network. Issued in October 2000, it claims a data network system for effecting coordination of a plurality of electronic devices, the system comprising a server microcomputer unit; a plurality of peripheral units which are battery-powered and portable, and which provide input information from the user or output information to the user; a radio frequency (RF) transmitter in the server microcomputer unit for sending commands and synchronizing information to peripheral units; RF transmitters and receivers in the peripheral units; a receiver in the server microcomputer to receive information transmitted by the peripheral units; and the operation of transmitters in the server and peripheral units being energized at low duty cycle RF bursts at intervals which are determined to be timed in relation to synchronizing information. The resulting invention substantially reduces both power consumption and interfering signals when using RF wireless communications to connect peripheral computing units, such as a mouse or keyboard, with a main computer.

The Dispute

In November 2013, DSS Tech filed suit against Apple in the Eastern District of Texas, alleging that Apple’s products utilizing Bluetooth wireless communications to connect with peripheral devices, including the Mac Mini, iMac, iPod, iPad and iPhone product lines, infringed on claims of the ‘290 patent. In December 2014, the case was transferred to the Northern District of California. That same month, Apple filed two petitions for inter partes review (IPR) proceedings at the PTAB challenging the validity of the ‘290 patent on 35 U.S.C. § 103 grounds for obviousness. In June 2015, the PTAB decided to institute both IPRs and final written decisions issued the following June invalidated all challenged claims of the ‘290 patent.

There are a couple of interesting things to point out about the makeup of the panel conducting both of these IPR proceedings on the ‘290 patent. First, the same panel of Administrative Patent Judges (APJs) that decided to institute the IPRs also issued the final written decisions in both cases, a practice which, while common at the PTAB, flies in the face of statutes governing the PTAB and how some believe there should be different APJ panels between institution and final written decision phases

Second, one of the APJs in both cases was APJ Matt Clements. As we’ve reported before, APJ Clements has sat on the panel in multiple cases where Apple was the petitioner in a post grant proceeding (i.e., inter partes review (IPR) or covered business method (CBM) review). Clements used to represent Apple as a patent infringement defense lawyer. The significance being that if a trial were in an Article III district courts, he would have to recuse himself from the case over there being a direct conflict of interest posed by his former employment by one of the parties in the case. As of April 2nd, Clements has served as an APJ on 52 PTAB proceedings of the 403 total petitioned by Apple.

As is noted by the recent Federal Circuit decision to reverse the PTAB’s IPR holdings in these cases, the appeal centered on a dispute over the term “low duty cycle RF bursts”, which is an element of claim 1. DSS Tech argued that none of the submitted prior art disclosed any limitation about a server transmitter that was energized by low duty cycle RF bursts. DSS Tech conceded that one piece of prior art, U.S. Patent No. 5241542 (“Natarajan”), titled Battery Efficient Operation of Scheduled Access Protocol and issued in August 1993, disclosed a system for reducing power consumption in mobile units, but argued that Natarajan did not disclose doing the same for server transmitters. In the final written decisions, the PTAB acknowledged that Natarajan only described the mobile units, but because the base units incorporated similar wireless communications components as the mobile units, it would have been obvious to a person of ordinary skill in the art that the system taught by Natarajan could also achieve reduced power consumption if applied to the base units.

Federal Circuit Says Claims Not Obvious

In its analysis of the PTAB’s final written decisions, the majority panel of Judges O’Malley and Reyna found that the Board’s invocation of “a person of ordinary creativity” who would understand to apply the low-power RF technology to the base station in view of Natarajan was essentially related to the Federal Circuit’s standards on the use of “common sense” in making an obviousness decision. This standard stems from the Federal Circuit’s August 2016 decision in Arendi, where the appellate court found that the PTAB misapplied Federal Circuit standards on the permissible use of common sense in an obviousness analysis. “Here, the Board relied on a gap-filler—“ordinary creativity” instead of “common sense”—to supply a missing claim limitation,” the Federal Circuit’s decision in DSS Tech reads. Much like in Arendi, the Federal Circuit found that the limitation at issue in DSS Tech is not “unusually simple” nor was the technology “particularly straightforward.”

More specifically, the panel majority explained that the full extent of the Board’s analysis relating to obviousness was contained in a single paragraph. O’Malley explained:

After acknowledging that Natarajan does not disclose a base unit transmitter that uses the same power conservation technique, the Board concluded that a person of ordinary skill would have been motivated to modify Natarajan to incorporate such a technique into a base unit transmitter and that such a modification would have been within the skill of the ordinarily skilled artisan. Id. In reaching these conclusions, the Board made no further citation to the record. Id. It referred instead to the “ordinary creativity” of the skilled artisan. Id. (quoting KSR, 550 U.S. at 420-21). This is not enough to satisfy the Arendi standard.

Newman Dissents

Dissenting from the majority panel was Circuit Judge Pauline Newman, who argued that, “if the PTAB’s explanation is indeed inadequate, the appropriate appellate action is not to grant final judgment for the opponent.” Further, Judge Newman did not feel that the PTAB’s explanation of its obviousness analysis was inadequate, finding that the Board stated with reasonable clarity how the information contributed in the arguments presented by either side led to the obviousness finding.

Notwithstanding the strength of Judge Newman’s conviction, it is difficult to understand how using the phraseology “ordinary creativity” does anything other than harkens back to “common sense,” as was the conclusion reached by Judges O’Malley and Reyna.

    To the point of:

    It is astonishing that the Patent Trial and Appeal Board STILL does not have Rules of Conduct or any kind of Code of Judicial Ethics that applies to Administrative Patent Judges. This is inexcusable, period.

    This is LESS a function of the particular administrative agency of the USPTO, and more of the fact that the Executive branch has “streamlined” its ethical “oath” into a single statement for all executive employees.

    Seeing as how the Executive branch has mandated a “reduce two for every new one” rule making axiom, perhaps we can generate a few suggestions for reducing admin rules in exchange for a more reasonable ethical standard…

    As to:

    I am not aware of which statutes governing the PTAB that this flies in the face of.

    Quite in fact, given the long-standing ability of the Director to set (and stack) panels, this cannot be said to “fly in the face.” Of course, as I am sure that you would agree, the ability to set and stack panels (either overtly, or in the shadows with improper – that is, off the written record – influence) is an entirely ‘nother matter of concern.

    As to:
    In reaching these conclusions, the Board made no further citation to the record. Id. It referred instead to the “ordinary creativity” of the skilled artisan. Id. (quoting KSR, 550 U.S. at 420-21). This is not enough to satisfy the Arendi standard.

    THIS would be worthy of some further explication. What is the Arendi standard and what does it take to satisfy that standard? Is this explicated in the MPEP? Are examiners trained to apply this standard as to what the law of obviousness entails (so as to be able to apply that law properly in their examination protocol?

    I cannot tell you how many times that I have seen conclusory hand-waiving by examiners not only in first actions on the merits, but also in replies to those first conclusory findings with a boilerplate of “applicant’s remarks are not persuasive, followed by a mere repeat of the original examiner conclusory remarks. It typically takes at least one RCE cycle to fight this (including examiner interviews) – money that my clients have to spend and money that my clients should not have to spend.

    As to:

    Newman – here she may have a procedural point (but I believe that she has been inconsistent on this point), but misses on the substantive matter – granted it is rare that Judge Newman misses, but she too is human, after all.

    Hey Gene,

    That someone with such an obvious “conflict of interest” can sit on not one but many an adjudicatory panels is beyond the pale, and utterly scandalous. One can only hope that SCOTUS will sink IPRs in Oil States.
