AI confidence in this short overview: high
EnOcean sued for infringement of EP (UK) 1 611 663 B3; Defendants pleaded invalidity over GB Harding and EP Goiran. The court construed "an autonomous-power switch" as a distinct switching component and "a spring element" as a physical/mechanical spring, found Claims 1 and 3 obvious over Harding, and revoked the patent. The court also found Claim 3 not obvious over Goiran.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
The judge applied claim construction principles to treat a repeatedly described "element" as a physical component located in the device, not merely a functional force, and held that where prior art (even older work) discloses the relevant features such that a skilled person would reasonably adapt them, the claim lacks inventive step. Using those constructions, Harding rendered the patent claims obvious.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The judgment observed that a skilled person is assumed to read prior art with interest regardless of age and that commercial unattractiveness of pursuing an idea does not confer inventiveness; it also noted that terminology like "magnetic spring" was not shown to be part of the common general knowledge at the priority date.
