SiOnyx alleged that Hamamatsu, following an aborted attempt to form a business partnership involving devices that improve the detection of near-infrared light, had violated a non-disclosure agreement and obtained patents on SiOnyx technology without naming SiOnyx personnel as inventors. Hamamatsu filed twelve motions for partial summary judgment. Judge Saylor granted three of these, denied three, and deferred judgment on the remaining six.
Hamamatsu’s bid to prevail on breach of contract and unjust enrichment claims on statute of limitations grounds was denied. While the relevant events occurred longer ago than the six-year time period provided by the statute of limitations on these types of claims, Massachusetts law follows the discovery rule, by which the cause of action arises not when the events occurred, but when the plaintiff discovers or should reasonably have discovered. Here, there were issues of fact as to when SiOnyx should reasonably have become aware of these claims, brought about by Hamamatsu’s repeated assurances that it had developed the relevant technology on its own, independent from any knowledge acquired under the NDA. Judge Saylor denied summary judgment of breach of contract, finding issues of fact as to the scope of use of confidential information, while granting Hamamatsu’s motion with respect to the unjust enrichment claims of both SiOnyx and co-plaintiff Harvard, because under Massachusetts law, unjust enrichment cannot be found where there is a valid contract defining the rights of the parties. Applying First Circuit law, Judge Saylor denied Hamamatsu’s motion with respect to consequential damages on the grounds that the testimony offered in support of this theory, SiOnyx’s recollection of statements as to why a third-party agreement was terminated made by an executive of the third party, constituted an exception to hearsay under Rule 803(3) as a statement of intent or motive. Finally, he granted Hamamatsu’s motion that a SiOnyx employee was not a co-inventor on Hamamatsu’s patents, as the testimony of the employee was not sufficiently corroborated by documentary evidence.
