VirnetX Prevails as Supreme Court Denies Apple’s Writ of Certiorari Regarding Patent Damages Apportionment

On February 24, 2020, VirnetX announced the U.S. Supreme Court denied Apple’s petition for a writ of certiorari. Apple had asked the High Court to consider the Federal Circuit’s claimed misguided use of prior license agreements to calculate patent infringement damage awards without satisfying the Supreme Court’s precedent that an apportionment between patented and non-patented features of multi-component products be performed in every case.

In 2010, VirnetX Inc. and Leidos, Inc. (herein collectively, “VirnetX”) successfully sued Apple for patent infringement alleging that iPhone features such as FaceTime and VPN-on-Demand infringed four of VirnetX’s patents, each claiming technology that provided security over networks. VirnetX won a $368 million reasonable royalty damage award. On retrial in 2016, the jury again found that Apple infringed VirnetX’s patents and awarded Apple $439 million of damages.

In the second trial, VirnetX’s damages expert relied on six VirnetX settlement agreements with third parties and calculated a rate of $1.20 based on a simple average. Apple claimed the royalty rates varied by more than an order of magnitude and may have needed weighting since the royalty bases varied extensively in terms of units and dollars. Notwithstanding, VirnetX’s expert urged the jury to accept that Apple would have agreed to pay a $1.20 royalty per each infringing unit. Apple contended that all but one of the six licenses VirnetX relied upon were for conventional desk-top calling systems that bear no resemblance to its iPhone. Apple claimed VirnetX’s expert acknowledged he thought the licenses were apportioned but was not certain how. The jury accepted, and the Federal Circuit sustained, VirnetX’s assertion that Apple would have agreed to pay a $1.20 average royalty per unit for a total royalty amount of over $302 million.

Apple petitioned the Supreme Court to answer the question of whether the Federal Circuit’s reliance on prior licenses to determine reasonable royalty damages, without satisfying apportionment rules, conflicts with the Supreme Court’s precedent requiring apportionment in every case.

Apple contended that in the past five years, the Federal Circuit has adopted a loophole that allows patentees to recover inflated damages far beyond the value of the patented invention by skipping apportionment entirely through reliance on prior licenses agreements without providing evidence that the licenses are comparable or already apportioned. Apple cited recent cases including Time Warner Cable, Inc. v. Sprint Communications Co. (herein, “Time Warner”), Elbit Systems Land & C41 Ltd. v. Hughes Network Sys. (herein, “Elbit”), and Commonwealth Science & Industrial Research Organization v. Cisco Systems, Inc. (herein, “Cisco”) in which the Federal Circuit has affirmed reasonable royalty awards that avoid apportionment by relying on prior licenses.

Apple claimed that in each of the cases listed above, the Federal Circuit sustained the assertion that prior licenses already include apportionment since a licensee would pay precisely what it believed the patented technology was worth. In its petition to the Supreme Court, Apple argued that such an assertion is incorrect since royalty rates negotiated as settlement of litigation are likely artificially influenced by the litigation and therefore do not reflect the patented invention’s true contribution to the value of the end-product.

Furthermore, Apple expressed its worry that in future reasonable-royalty cases patentees will be able to draw upon what it calls a “Time Warner-Elbit-Cisco loophole” to avoid apportionment requirements simply through reliance on prior licenses.

Apple feared that patent owners will seek massive damage awards that will deter innovation and cause royalty stacking that far exceeds a product’s worth.

If this Court does not correct the Federal Circuit’s departure from long-established apportionment principles, patentees will seek massive, unjustifiable sums to license their patents, and will obtain inflated judgments in court. This will divert funds that would otherwise support technological innovation.

That makes apportionment ever more important. Without apportionment, rates will stack one upon the next, growing to an exorbitant sum far exceeding the product’s worth. This well-documented phenomenon, called “royalty stacking,” has predictable consequences: Plaintiffs can credibly threaten grossly excessive damages and coerce massive settlements. At best, that ties up resources better spent by innovators on research and development. At worst, it deters innovators from entering a market altogether.

Commercially Reasonable Efforts - How an Expert Can Help

By: Peter Crosby

Imagine this scenario: Early stage company Smallco develops an exciting new technology, which it uses to create the prototype of its first product - Brakethroo! A large company in the same field, Bigco, becomes aware of Brakethroo, and realizes that if the product works as hoped, it could be a valuable addition to Bigco's product range. Bigco offers to buy the technology and product from the shareholders of Smallco. The merger and acquisition (M&A) agreement specifies an up-front payment, and one or more payments dependent on achievement of milestones. Bigco agrees to use "commercially reasonable efforts" to achieve the milestones. Smallco and Bigco sign the agreement, the shareholders of Smallco get an immediate payout and look forward to further milestone payments.

Adjusting the Balance in SEP Evaluations and Licensing

By: Keith Mallinson

A European Commission DG Growth initiative described in its Roadmap on Standard Essential Patents for a European digitalised economy aims to increase information on SEPs so implementers can get a better idea about which of these they might be infringing. Additional disclosures on how patent claims might read on the standards could be beneficial. Requirements should reflect the dynamics and uncertainties in standards development and patent prosecution and must not be onerous to patent owners. These are issues for standards development organisations to consider.

Marked Recovery

By: Antonio R. Sarabia II

EIGHT YEARS AGO Congress decided that the existing means for awarding damages for trademark infringement were not deterring this illegal practice and decided to supplement these measures with statutory damages-a specific range that a court could award even in the absence of proof of a plaintiff's losses or the defendant's profits.
