German Court Upholds Rejection of KPN's Patent Infringement Appeal Against OPPO

WISECODE Take

This news highlights a common misconception among business owners: even large telecom operators like KPN can face repeated setbacks in international patent litigation due to the insufficient validity of their patent claims, despite believing that owning patents makes them invulnerable. From a business management strategy perspective, KPN's series of patent lawsuits against OPPO resemble a company attempting to solidify or expand market share through patent barriers. However, the German Federal Court of Justice (BGH) definitively rejecting KPN's appeal in the EP 2 291 033 patent case (case number: X ZR 103/24) and upholding the invalidity of claim 14, is akin to a company's core product being found with fundamental design flaws, thereby undermining its market strategy. With three out of five lawsuits filed by KPN in Germany and the UPC resulting in patent invalidation or non-infringement, it is clear that the quality of its patent portfolio faces severe challenges. For business owners, this signifies that patent strategy should not merely focus on quantity, but critically emphasize the quality and enforceability of its claims. Otherwise, even substantial litigation investments could lead to patents being declared invalid or non-infringed, thereby depleting corporate resources, damaging reputation, and missing market opportunities. Firstly, companies should regularly conduct strength assessments and invalidity analyses of their own and competitors' patent portfolios to ensure core patents possess sufficient stability to withstand legal challenges. Secondly, when engaging in international patent landscaping, it is crucial to thoroughly understand the differences in patent laws across various countries and precisely draft and optimize patent claims based on the product characteristics in target markets. Patents are a company's shield and spear in competition; their sharpness and resilience stem from solid quality.
