(“EP 938”)and the divisional of EP 938, EP 2 706 425 B1
(“EP 425”).Belparts has also not substantiated that Belimo infringes EP 938 and EP 425, which hinders a further substantive reply in this respect.
3.Het geschil
date] that actions relating to our Belimo 6-way valve and Belimo 2-way valve and 3-way valve infringe Belparts’ patents and that this product can no longer be sold, shipped, used, offered, or stored in the Netherlands and in [
countries].
datum] heeft beslist dat handelingen verricht met onze Belimo 6wegklep en Belimo 2-wegklep en 3-wegklep inbreuk maken op de octrooien van Belparts en dat dit product niet langer mag worden verkocht, verscheept, gebruikt, aangeboden of opgeslagen in Nederland en in [

4.De beoordeling
Bevoegdheid
orifice adjusting system“
contributes to the accuracy of the flow measurement, compared to a positioning in front of the orifice adjusting system. Appellant has found that the measurement of flow sensors positioned in front of the orifice adjusting system can suffer from the occurrence of pressure waves in the liquid medium which may frequently occur in hydronic systems when somewhere a valve is closed and which are reflected at the orifice, thus disturbing the flow measurement.”
