Today, Nexam announced that it has received notice that the European Patent Office (EPO) has granted the company’s patent application regarding its crosslinking technology for aromatic polyetherketones. The decision will take effect on June 25, when the patent is published.
This is the second such positive news this week, following Monday’s announcement that Nexam has received a notice of allowance from the US Patent Office (USPTO) stating that it intends to grant Nexam’s US patent application for PETA, which is a unique and for Nexam very important product for crosslinking a large number of polymers.
PETA is a new and unique molecule that improves the properties of e.g. polyimides, nylons and polyesters. Nexam developed PETA with the aim of getting a crosslinker with lower curing temperature. Global production of plastics where PETA could be used comprises more than 20 million tons / year.
According to Nexam, PETA is being evaluated by a large number of potential customers, whereof several are world leading in their respective areas. It concerns e.g. electronics applications, increased efficiency and improvement of manufacturing processes, and improvement of temperature resistance and service life of the materials.
”We developed the PETA molecule since many of our potential customers requested the type of functionality that the molecule offers. PETA can definitely help our customers develop better and cheaper solutions. We are first in the world with this product and it’s exciting to see that the patent application we filed a couple of years back now also has resulted in a patent in USA. This gives Nexam a 20-year protection against competitors in this market.”, says Daniel Röme, Director of Business Development and Innovation
As previously announced, the corresponding European application has also been granted (see press release from April 25, 2013). The granting of the application in USA will further strengthen Nexam’s protection for the crosslinking technology developed by the company. In addition, Nexam has applied for PETA patents in other markets – including China, Japan, South Korea, Russia and Brazil.
Nexam currently has, in addition to already approved patents, 35 patent applications within 12 patent families.
