German PV materials manufacturer Heraeus has added an additional product to a patent infringement lawsuit it filed against Taiwan’s Giga Solar Materials in June.
Heraeus has added its No. 610 Front Side Silver Paste product to the complaint which originally included various other front-side metallisation pastes.
The manufacturer is seeking undisclosed damages for the alleged infringement and treble damages if it is proved to be wilful, including a permanent injunction to prevent Giga Solar manufacturing, using, offering or selling the products again.
Andreas Liebheit, head of Heraeus Photovoltaics’ global business unit, warned that industry suppliers could not continue to justify investments into products if intellectual property is infringed.
“Fair competition encourages the development and improvement of technology which benefits the entire industry. It is important for us and the industry to challenge potential violators who can potential[ly] hinder the technological advancement of the PV industry.
“If suppliers are not able to gain full economic benefit from investments in technology and intellectual property, then why should anyone invest? We will defend all our technology for the long term benefit of the industry,” he added.
Heraeus strengthened its IP patent portfolio earlier this week with the purchase of a number of patents from Murata Manufacturing regarding lead-free solar cell pastes.
