Scientific Plastic Products, Inc., v. Biotage AB.

September 10, 2014

Panel:  Newman, Moore and Wallach.  Opinion by Newman. Dissent by Moore.

Summary

The CAFC affirmed the Patent Trial and Appeal Board’s decision that all claims of the three disputed patents held by Scientific Plastic Products, Inc. (SPP) would have been obvious.

The CAFC held that the cited references, King and Strassheimer, both of which related to the sealing of a beverage container, were available as prior art against the claimed resealable cartridge for low pressure liquid chromatography (LPLC).

The CAFC held that although the cited reference Yamada failed to explicitly disclose a leakage problem, by “providing for the presence of an O-ring,” Yamada implicitly acknowledged that there is the potential for a leak. Further, the CAFC concluded that the inventors, in the patents in question, identified that the potential for leaks is a “known problem.”

Accordingly, the CAFC found adequate reason for one of ordinary skill in the art to turn to King or Strassheimer to improve the sealing arrangement set forth in Yamada.
