Magistrate Judge K. Nicole Mitchell of the Eastern District of Texas recently denied patent owner Cellular Communications Equipment LLC (“Cellular” or “CCE”) motion for summary judgment that its asserted patents were not essential to a cellular standard, ruling that there was a factual dispute based on statements made by patent owner Cellular during the litigation. This case illustrates problems in loosely referring to standard essential patents generically as patents relevant to a standard or erroneously stating that a patent was “declared essential.” Declarations that patent owners submit to standard setting bodies typically do not declare that patents are essential to the standard, but identify patents that may be essential to the standard and what licensing terms, if any, they would offer if the patent actually is essential. A patent is not actually a “standard essential patent” or “SEP” unless it is “essential” to the standard under the standard setting body’s intellectual property rights (IPR) policy.
Further, this case illustrates that, just because a patent is infringed by one way of implementing the standard does not mean that the patent covers every way to implement the standard and, thus, may be “essential” and subject to a standard-setting licensing commitment.
In sum, for convenience, speakers, writers and parties may loosely talk about a patent or patent portfolio as being SEP(s) as a short-hand for patents that were declared potentially an SEP. But, when making statements on which a court, agency or other decisions may rely, it may be helpful to be more precise or provide a caveat that the term SEP is being used as a short-hand and does not mean that a patent actually is essential to the standard.
