The sprawling patent infringement action in the Northern District of Illinois involving Innovatio IP Ventures is often in the headlines not because it involves standard-essential patents, but because it involves (in part) patent infringement claims brought by a non-practicing entity (Innovatio) against “end users” (coffee shops, hotels, restaurants, etc.).  But last Friday, Judge James F. Holderman issued a ruling that may be the first of its kind for a district court — a ruling addressing the “essentiality” of patent claims, separate and apart from the issue of infringement.  If you’re not familiar with this case (and even if you are), bear with us — we’ll try to explain just why this ruling is so “essential” (sorry).

[2013.07.26 (Dkt 851) Order re Essentiality]

Warning — this is going to be a long post.

You can catch up in more detail on the background of this case here, but here’s the gist of what has happened so far (this is also summarized a bit in Judge Holderman’s order): Innovatio purchased a number of old Broadcom patents, and asserted these patents against entities that provide WiFi services (via the IEEE 802.11 standard) to their customers, and several of the vendors of these WiFi products (Cisco, Motorola Solutions, Netgear, and others) stepped in, seeking declaratory judgments that neither they nor their customers infringed Innovatio’s patents (and also that the patents are invalid).  In addition, the WiFi vendors claimed that Innovatio violated its RAND obligations, the antitrust laws, and even the RICO Act through its licensing and litigation campaign.  Although the RICO and antitrust claims were dismissed, the issues of infringement, validity, and RAND obligations remain in the case.

Given the large number of asserted patents and claims (~30 patents and hundreds of claims), the parties decided that the best course of action would be to address Innovatio’s potential damages award first — prior to any decisions on infringement or invalidity — because the WiFi vendors claimed that any damages would be limited by RAND obligations entered into by Broadcom (to which Innovatio would be bound).  The parties agreed that all RAND-related issues, including both the alleged essentiality of the claims and any RAND limitations on damages, would be decided by the court (as opposed to a jury).

Over the past several months, the parties briefed the disputed issue of essentiality (see here, here, and here) and the court held a bench trial on July 18-19.   To be clear, the WiFi vendors still dispute that they infringe Innovatio’s patents — their contentions on essentiality are based on Innovatio’s infringement contentions (the infringement issue will be addressed later, if at all).  Where the parties disputed whether Innovatio’s claims were essential to the 802.11 standard, they separated the claims into a number of technological “buckets” to be evaluated by the court.  All in all, the court had to make an essentiality determination on 168 claims.  And in the end, Judge Holderman found each of these claims to be essential to the 802.11 standard and subject to the IEEE-related RAND obligation.

Burden of proving essentiality is on the party asserting the RAND defense

First, Judge Holderman addressed the disputed issue of which party bears the burden of proof on the essentiality issue — and he found that this burden was more appropriate assigned to the WiFi vendors, who were the ones asserting that the RAND framework applied.  The court likened this to a license defense, and placed the burden on the WiFi vendors.  The alternative, according to the court, would be that in ANY potential standard-essential patent case, the default rule would be that a RAND obligation applied unless the patent owner proved otherwise — a rule that would be overly burdensome on patent owners.

The RAND obligation applies to individual patent claims, not entire patents

The WiFi vendors argued that Innovatio was bound to license entire patents on RAND terms, as opposed to individual claims — citing certain letters of assurance submitted by prior owners of some of the patents-in-suit.  But after examining the IEEE Bylaws — which use the term “Essential Patent Claims” — the court concluded that the RAND obligation applies separately for each individual claim within a patent, not an entire patent.  With that, the court turned to the disputed claims at issue.

The court finds all of Innovatio’s asserted claims to be 802.11-essential

At pages 18-20 of the opinion, the court does an excellent job of framing the parties’ dispute.  The WiFi vendors argued that wherever Innovatio referenced the 802.11 standard in its infringement contentions, that meant that the claims were alleged to be essential.  The court disagreed, noting that mere reliance on the standard does not mean that the claim is alleged to be essential.  The court also rejected the WiFi vendors’ claim that Innovatio’s patents were essential because the allegations were only directed to 802.11-compliant products, noting that even 802.11-compliant products can contains countless other (non-standard-essential) features.

But despite that, the court concluded that each of Innovatio’s asserted claims were essential to the 802.11 standard and bound by the RAND obligation.  We won’t get into the individual analysis of each of the categories here, but one theme was common throughout that warrants mentioning — the court’s repeated rejection of Innovatio’s argument that the presence of claim elements not expressly required by the standard rendered the patent claims non-essential.  Importantly, the court used the following standard (pulled from the IEEE Bylaws) to determine essentiality:

To prove that a patent claim is standard-essential, an accused infringer must establish by a preponderance of the evidence that (1) at the time of the standard’s adoption, the only commercially and technically feasible way to implement a particular mandatory or optional portion of the normative clauses of the standard was to infringe the patent claim;5 and (2) the patent claim includes, at least in part, technology that is explicitly required by or expressly set forth in the standard. (Op. at 18.)

The court repeatedly found that the “extra” elements in Innovatio’s claims represented the only “commercially feasible” way of implementing the standard in the particular devices at issue.  It also found that a RAND obligation on an independent claim “would be meaningless” if a patent holder could simply charge an exorbitant fee on a dependent claim that additionally recited technically basic, non-novel technology (think of a standard-compliant device wherein the device also includes a red LED light).

There’s a lot to digest in the 49-page opinion, and we’ve only done a fairly high-level summary in the 1000+ words here.  We may do a follow-up post or two in order to get into the nitty-gritty of some of Judge Holderman’s opinion in the coming weeks.  The court also held a status hearing yesterday to set some further dates relating to discovery and pretrial issues.  The bench trial on RAND issues is set for September 9-12, 2013 — and it promises to be an interesting one.
