Pax Sentinel - Appeals Court Rebuffs Bid for Total Seat Power Profits

The Court of Appeal of England and Wales has rejected an attempt by Lufthansa Technik to capture the entire profit margin generated by global aerospace suppliers selling in-seat electrical socket systems. In a judgment delivered on July 27, 2026, with Neutral Citation [2026] EWCA Civ 964, the appellate court dismissed the maintenance subsidiary's claim to 100 percent of the commercial returns earned by suppliers Astronics, Panasonic and Safran from their EmPower Fusion cabin power units. The three-judge panel also ruled in favor of the equipment manufacturers regarding licensing rights, deciding that Lufthansa Technik's financial recovery must be reduced to account for an earlier commercial settlement reached by its former development partner. Cabin Power Technology The litigation focuses on hardware familiar to commercial airline passengers: the integrated power sockets installed in aircraft seats to charge personal laptops, tablets and smartphones during flight. Lufthansa Technik, the maintenance and engineering arm of the Lufthansa Group, holds European patents on safety apparatuses designed to regulate and deliver electrical current safely to in-seat sockets without risking electrical shocks or cabin hazards. Major seat and avionics manufacturers, including Astronics, Panasonic and Safran, built and installed these integrated systems into aircraft cabins operated by airlines worldwide under the EmPower Fusion brand name. After English courts confirmed that the suppliers had infringed the valid patent, Lufthansa Technik chose not to seek traditional damages, which compensate a patent owner only for its own lost sales. Remedy Election Instead, the company elected to pursue an account of profits. This legal remedy compels an infringing supplier to surrender the actual commercial profits it earned by selling the contested equipment. At first instance, the High Court awarded Lufthansa Technik $4.42 million from Astronics, $7.384 million from Panasonic and $567,800 from Safran. The trial judge arrived at these figures by applying an apportionment rate of 13 percent, using historical licensing terms as a benchmark for the patent's contribution to the total seat power unit. Lufthansa Technik appealed that award, arguing that because the suppliers had no immediate non-infringing alternative, it was entitled to seize 100 percent of the suppliers' overall system profits. The Court of Appeal rejected that argument. The court ruled that total profits can only be stripped when a patented invention represents the essential ingredient without which the complete product could not exist in the market. Writing for the court, Lord Justice Arnold said that fair apportionment remains the standard legal mechanism when other factors, including manufacturing quality, technical specifications and customer support, drive the broader commercial sale. Single Pot of Profits The appellate court delivered a further financial setback to the carrier by upholding the manufacturers' cross-appeal regarding KID Systeme, a German avionics supplier that held an exclusive license under the patent during earlier development phases. The judges determined that because KID held exclusive manufacturing and marketing rights under a 1998 agreement, those rights occupied a defined share of the single pot of recoverable profits. Because KID previously settled its own infringement dispute with an Astronics predecessor, the court ruled that Lufthansa Technik cannot retroactively claim those compromised earnings. Lord Justice Arnold said that the law does not permit a patent owner to take profits attributable to rights that were transferred to an exclusive licensee, even if that licensee has already settled its legal claims. European Claims The court dismissed the suppliers' attempts to block interest awards and parallel claims across continental Europe. The panel confirmed that pre-judgment interest applies from the date of the first infringing act, compensating the patentee for the retention of funds over time. The judges also refused to declare the English financial awards provisional while parallel infringement lawsuits proceed in France and Germany. The court determined that foreign judiciaries must apply their own domestic legal frameworks to prevent double recovery. The commercial litigation highlights the carrier's ongoing focus on extracting auxiliary revenue from aircraft cabin hardware, even as the parent conglomerate faces broader margin pressures analyzed in our report on how [plunging operating profits prompt further passenger fare hikes](/en/article/YcKwfI86_plunging-operating-profits-prompt-further-passenger-fare-hikes).
