Solannex Strikes Again, Accuses Nanosolar of Patent Infringement

3

In a previous post, I wrote about Solannex’s patent infringement suit against Santa Clara, California, thin-film photovoltaic (PV) company MiaSolé.

Solannex struck again earlier this month, this time accusing San Jose-based Nanosolar of patent infringement.

The complaint is not publicly available, so we don’t know which patent(s) Solannex is asserting, but a report on the filing of a patent or trademark suit (Solannex-Nanosolar_Report) submitted to the U.S. Patent and Trademark Office indicates the suit was filed in U.S. District Court in Oakland on February 4th.

The MiaSolé case involves Solannex’s U.S. Patent No. 7,635,810, entitled “Substrate and collector grid structures for integrated photovoltaic arrays and process of manufacturing such arrays,” (’810 Patent).

The ’810 Patent is directed to interconnection structures for PV cells including electrically conductive “fingers” that allow electrical communication between the top and bottom surfaces of an interconnect region.

See my post about the MiaSolé case for a more detailed discussion of the ’810 Patent.

It’s hard to predict how wide a net Solannex will cast with its patent enforcement activity. But one thing is for sure: if you’re in thin-film, be careful where you point your fingers.

    Seems to me that companies are pushing harder than before to compete with competitors without doing the actual work of inventing new things rather just building on the work of others I think as this trend continues so will the cases of patent infringement and patent litigation increase.

    So, wait… is a patent troll trying to shake down a conman?

    That’s what this seems to boil down to. And it will probably work. The last thing nanosolar wants is to be found out through a court case related to some of their technology claims.
