Patent valid and infringed (Article 25 UPCA , Article 65 UPCA).
Claim interpretation (Article 69 EPC).
Claim 6 - input fiber bundle: the term “an” must be understood as a numeral.
Contrary to the defendant’s view, feature 6.1.1.1 provides for only one inner input fiber, which serves as a clear reference point for (at least) one set of input fibers arranged radially outward.
The wording “an inner fiber” already points in this direction, […] especially since the relevant original language does not state “[only] one inner fiber.”
Infringement - literal use of the teaching of claim 6 of the patent. (Article 25 UPCA)
Features 6.1.1, 6.1.1.1, 6.1.2, 6.2, and 6.3.1 are also realized.
