Plain-English summary
Insulet Corporation obtained a default infringement judgment against EOFLOW Co. Ltd. (maker of the EOPatch insulin pump) at the Milan Central Division concerning EP 4 201 327, a wearable fluid delivery device patent. EOFLOW failed to defend the proceedings. The court confirmed infringement and granted an injunction, recall, information order, and damages from 19 June 2024. EOFLOW's own revocation action was dismissed for lack of prosecution.
Accepted arguments
What the court agreed with — by party.
Default judgment warranted after verification of sufficient, precise and consistent evidence
ClaimantLegal basis: Rule 355.2 RoPNote: Milan Central Division confirmed it must verify adequacy of evidence before issuing a default decision; a procedural violation alone is insufficient basis for default judgment.
Patent terms must be interpreted according to their principal functional meaning without result-oriented avoidance of infringement
ClaimantLegal basis: Art. 69 EPCNote: Court applied straightforward reading of claims and drawings in interpreting the wearable insulin delivery device patent, finding infringement by the EOPatch product.
Costs cap applies per court instance regardless of number of parties or patents
ClaimantLegal basis: Art. 1(3) Administrative Committee decision of 24 March 2023Note: Where infringing manufacturer and distributor are in separate parallel proceedings concerning same patent and same act, a unitary approach to the costs cap is warranted to avoid violation of the cap.
Rejected arguments
What the court did not agree with — and why.
No rejected arguments captured.

Claim construction notes
The Milan Central Division applied a 'patent lexicon' approach, holding that patent terms carry their own meaning derived from the patent itself. Claims are to be interpreted following a straightforward reading of claims and drawings without looking, in a result-oriented manner, for a way out of a possible infringement; terms must be interpreted according to their principal functional meaning.
