    Infringement Action

    The judge-rapporteur partially granted Avient's R.190 RoP application for evidence production. The Xingi Group was ordered to produce at least 30 kg each of two specified UD Fabric types (J300_120H_2UD and J300_130S_4UD) and the English version(s) of an Introduction Video removed from its website. Requests for internal ballistic test data and internal communications regarding the video removal were dismissed as unnecessary or disproportionate.

Accepted arguments
What the court agreed with — by party.

  • Prima facie case of infringement of claims 13-15 exists based on evidence of infringement of claims 2-4 and 8-10; ballistic testing of UD Panels is necessary and relevant to establish infringement of claims 13-15

    ClaimantLegal basis: R.190 RoP, Art. 59(1) UPCA

  • UD Fabrics are not available in sufficient quantities through ordinary commercial channels (B2B supply chain only), justifying evidence production order

    ClaimantLegal basis: R.190(1) RoP, Art. 6 Enforcement Directive 2004/48/EC

  • 30 kg of each UD Fabric type is necessary for in duplo ballistic testing according to patent methods; quantity not reduced

    ClaimantLegal basis: R.190 RoP proportionality requirement

  • Introduction Video is plausibly necessary to establish infringing acts directed at UPCA territory; video was removed from Xingi's website during proceedings

    ClaimantLegal basis: R.190 RoP, Art. 59(1) UPCA
Rejected arguments
What the court did not agree with — and why.

  • Request for six UD Fabric variants is necessary and proportional; infringement must be established across the full product range

    ClaimantLegal basis: R.190 RoP proportionality — court limited order to two alternative fabric types

  • Internal ballistic test reports, V50 test results and Eabs calculations should be produced as they are necessary for deciding the case

    ClaimantLegal basis: R.190 RoP necessity — internal data not generated under patent-specific test conditions and therefore not necessary

  • Internal communications regarding decision to remove/replace the Introduction Video should be produced

    ClaimantLegal basis: R.190 RoP — dismissed as unnecessary and disproportionate at this stage

  • Application should be dismissed in its entirety; R.190 threshold not met; infringement case not sufficiently substantiated; no basis for general discovery

    RespondentLegal basis: R.190 RoP — partially rejected; court found prima facie infringement case and ordered partial evidence production

  • Avient was able to acquire UD Fabrics on the market, so evidence production is not necessary

    RespondentLegal basis: R.190 RoP necessity — dismissed; small amounts obtainable on market insufficient for required ballistic testing

  • Introduction Video is not necessary to establish technical infringement

    RespondentLegal basis: R.190 RoP — dismissed as irrelevant; video sought to prove infringing acts in UPCA territory, not technical infringement
