Court Finds Patent Claims Essential to Wi-Fi Standard Because They Cover Technology Required by the Standard and There Are No Commercially or Technically Feasible Noninfringing Alternatives

Authored by D. Brian Kacedon, Sydney Kestle, and John C. Paul

Courts have increasingly found themselves facing issues related to patents essential to standards and the associated obligations imposed by standards-setting organizations. One such standards-setting organization is the IEEE, which established the 802.11 standard for wireless networks. Devices that comply with the 802.11 standard can easily communicate with each other in any WLAN. To comply, devices must use the technology described in the standard. This requirement can provide significant benefits to companies owning patents covering the standards-essential technology. To curb potential market manipulation, the IEEE requires that owners of standards-essential patents offer licenses to those patents on reasonable and nondiscriminatory terms (often referred to as "RAND"). In re Innovatio IP Ventures, LLC Patent Litigation¹ the court held that a patent claim was essential to the 802.11 standard if (1) there is no commercially or technically feasible way to avoid infringing the claim and (2) the patent claim describes technology explicitly required by the standard.

Innovatio had purchased 23 patents for wireless technology. As the 802.11 standard was finalized, the previous owners of Innovatio's patents sent letters to the IEEE, agreeing to license any standards-essential technology covered by their patents on RAND terms.

Anticipating a patent-infringement suit, a group of manufacturers of 802.11-compliant devices filed a declaratory-judgment action against Innovatio, seeking a declaration of noninfringement and invalidity. Innovatio countersued, alleging infringement. At the outset, the parties and the district court agreed to first determine the potential damages available to Innovatio. The manufacturers argued that Innovatio's patents contain claims essential to the 802.11 standard and, therefore, that Innovatio must honor the previous patent owners' commitments to license those patents on RAND terms. Further, the manufacturers argued, this RAND obligation necessarily limited Innovatio's potential recovery to no more than a RAND royalty.

The Innovatio Decision

The district court relied on the IEEE Bylaws and Federal Circuit law to resolve the dispute. Noting the IEEE Bylaws, the district court reiterated that a patentee is obligated to license only individual standards-essential claims, not entire patents, on RAND terms. Analogizing a RAND obligation to a license (a contractual commitment limiting the liability of an infringer), the district court further stated that alleged infringers bear the burden of showing that a RAND obligation exists—namely that a claim is standards-essential. According to the court, "the alternative would be to assume in patent litigation that every potentially standard-essential claim is subject to RAND until the patent owner demonstrates otherwise, a rule that would be overly burdensome for patent owners." Thus, this case turned on whether the disputed claims were essential to the 802.11 standard.

The parties agreed that the IEEE Bylaws dictate the meaning of an "essential patent claim." According to the Bylaws, an essential patent claim includes any claim "the use of which was necessary to create compliant implementation," so long as there is "no commercially and technically feasible noninfringing alternative." The Bylaws include an exception: an essential patent claim does not include any claim "essential only for Enabling Technology." Enabling Technology is any technology necessary for, but not explicitly required by, the standard. Construing the Bylaws to avoid rendering any provision superfluous, the district court concluded:

If a patent claim recites only technology that is necessary to implement the standard, but that is not explicitly required by or expressly set forth in the standard, then the claim is not standard-essential, even though it is "necessary" within the meaning of the first sentence. By negative implication, however, a claim directed to both Enabling Technology and to explicit steps of the standard is essential.

The manufacturers argued that, in addition to the court's definition, "a compliant implementation" requires a compliant device (such as a laptop, an access point, or a barcode reader) and not just a standardized feature. Accordingly, they suggested that a claim is standards-essential if any compliant device infringes the patent claim. The district court disagreed, noting "one does not usually speak of ‘implementing' a device. . . Instead one ‘implements' a standardized feature." Moreover, the Bylaws specifically refer to "a compliant implementation of either mandatory or optional portions."

Determining Whether Claims Are Essential to a Standard

Having defined the contours of a standards-essential claim, the court analyzed different groups of asserted claims to determine whether each of these groups was standards-essential.

Many of the claims the court examined recited features or functions necessary to implement an optional portion or an optional mode of the standard. The use of those functions or features defined in the standard would infringe the claims and, as a result, the court found those claims standards-essential.

For some of the other claims, Innovatio had proposed noninfringing alternatives, which were intended to show that the claims are non-standards-essential because the standard can be implemented without infringing the claims. But the court found that Innovatio's proposed noninfringing alternatives either still infringed or were not technically or commercially feasible. For example, one of Innovatio's proposed noninfringing alternatives would slow communication and cause data to be lost, which made that proposed noninfringing alternative not technically feasible. As a result, the court found these claims standards-essential.

For other claims, the court found that although the claimed technology was not technically part of the standard, the industry had coalesced around using the claimed technology, noting that Innovatio was not able to identify any devices on the market lacking the claimed technology. Thus, there was no commercially feasible alternative to using the claimed technology to implement the standard, which led the court to find that those claims too were standards-essential.

The court also looked at some dependent claims that added a single element to other standards-essential independent claims. But this additional element—such as a keyboard or a processor—the court noted, was too basic. The court rejected Innovatio's argument that the dependent claims were nonstandards- essential because, as the court explained, allowing a dependent claim that adds a basic additional element to be non-standards-essential would render the RAND obligation meaningless. In other words, a company could agree to license the standards-essential independent claim but then avoid that obligation by simply adding a dependent claim that adds a basic additional element (such as a keyboard).

In discussing this issue, the court also addressed "Enabling Technology" as defined by the IEEE. Innovatio argued that the additional element in the dependent claim did not recite Enabling Technology because it was not necessary to make or use something that complies with the standard. The court likewise rejected this argument, explaining that it would permit companies to avoid RAND obligations by claiming a subset of Enabling Technology (for example, a keyboard rather than a data-input device) and then arguing that the unclaimed subset of Enabling Technology provided a noninfringing alternative. For these reasons, the court found that the dependent claims that added basic limitations to standards-essential claims were likewise standards-essential.

In short, then, the court found all of Innovatio's claims to be standards-essential, for the various reasons listed above. Because the court determined that the claims are standards-essential, it subjected those claims to Innovatio's RAND obligations.

Strategy and Conclusion

The bylaws and other rules of a standard setting organization form a starting point to determine whether patents relating to standardized technology carry potential obligations to license the patents under reasonable and non-discriminatory conditions. Depending on the particular standards-setting organization, standards-essential claims could potentially include claims that read on optional features of the standard, dependent claims that add basic elements to standards-essential claims, and claims that are not necessarily required by the standard but that the industry has nevertheless coalesced around.
