Advanced Cell Diagnostics, Inc v Molecular Instruments, Inc

Advanced Cell Diagnostics, Inc v Molecular Instruments, Inc

The patents are invalid for obviousness over Collins in combination with Kern. The skilled person, motivated by the prior art, would have found it obvious to use bDNA with cruciform probes in situ, with a reasonable expectation of success. There was no technical prejudice or mindset deterring the skilled person from making this combination. The patents are not anticipated by Collins or Collins with Kern, as the disclosures do not meet the standard for anticipation. Had the patents been valid, MI's acts of bespoke troubleshooting with customers would have made it jointly liable for infringement of EP572, but not EP439, under the proper construction of the claims.

There was no technical prejudice or mindset deterring the skilled person from making this combination. The patents are not anticipated by Collins or Collins with Kern, as the disclosures do not meet the standard for anticipation. Had the patents been valid, MI's acts of bespoke troubleshooting with customers would have made it jointly liable for infringement of EP572, but not EP439, under the proper construction of the claims.
