The Shanghai-based photo voltaic growth firm filed two complaints with the Munich and Hamburg native divisions of the Unified Patent Court.
Chinese photo voltaic module producer JA Solar has initiated patent infringement proceedings towards an unnamed rival module producer earlier than Germany’s Unified Patent Court (UPC).
The two complaints, filed by the Munich and Hamburg Local Divisions of the UPC, are aimed on the competing vary of TOPCon photo voltaic modules and concerning the infringement of JA Solar’s patents EP 2 787 541 B1 and EP 4 092 759 B1, the corporate mentioned in an announcement.
“The abbreviation ‘TOPCon’ stands for ‘tunnel oxide passivated contact’ expertise, which has grow to be the state-of-the-art and market customary for crystalline silicon photo voltaic cells,” mentioned JA Solar.
“The first patent, EP 2 787 541 B1, covers the attribute layer construction of TOPCon photo voltaic cells, together with an ultra-thin tunneling silicon oxide (SiO2) layer and a skinny extremely doped polysilicon layer organized on the again floor of the silicon wafer, permitting electrons to go by because of the quantum tunneling impact, and on the similar time successfully lowering the consequences of recombination, thus enhancing the effectivity of the cells,” it added. “EP ‘541 has a remaining life till 2034 and has been validated in Germany, the Netherlands, Italy and France, in addition to the UK.”
The second patent, EP 4 092 759 B1, pertains to the association of electrodes, consisting of finger traces and bus bar traces, of the photo voltaic cell and the leads connecting a photo voltaic cell to PV panels. “This is a component of a bigger patent household concerning the construction and association of the electrode and connecting leads present in most present TOPCon photo voltaic modules available on the market,” the corporate defined. “EP ‘759 is not going to expire earlier than 2035 and is validated as a Unitary Patent and subsequently will be enforced with impact in all contracting states which can be members of the UPC.”
The UPC is a typical supranational patent court docket of the 17 EU members. Established final yr, it hears instances concerning infringement and revocation proceedings of European patents. A court docket resolution is immediately relevant to member states which have ratified the UPC Agreement.
“For JA Solar, IP is not only a buzzword; it is a dedication, and our robust stance on patents ensures that our groundbreaking expertise leads the way in which,” commented a JA Solar spokesperson. “We have a accountability to guard our management place and can proceed to implement our patent rights towards those that attempt to promote infringing merchandise in Europe and different markets.”
