Trump’s Lawyers Will Get Away with Facilitating His Anti-Democratic Antics and They Know It

AUSTIN SARAT

Austin Sarat—Associate Provost and Associate Dean of the Faculty and William Nelson Cromwell Professor of Jurisprudence & Political Science at Amherst College—predicts that because the lawyer discipline process is broken, President Trump’s lawyers will get away with facilitating his anti-democratic misconduct. Professor Sarat notes that Lawyers Defending American Democracy (LDAD) released a letter calling on bar authorities to investigate and punish members of Trump’s post-election legal team, but he points out that while LDAD can shame those members, it still lacks the ability itself to discipline or disbar.

Sionyx LLC v. Hamamatsu Photonics K.K.

Court: US Court of Appeals for the Federal Circuit

Docket: 19-2359

Opinion Date: December 7, 2020

Judge: Alan David Lourie

Areas of Law: Intellectual Property, Patents

Mazur discovered a process for creating “black silicon” by irradiating a silicon surface with ultra-short laser pulses to create a textured surface; the resulting black silicon has electronic properties different from traditional silicon. Several patents issued, including the 467 patent, from a 2001 patent application. SiOnyx was formed to commercialize black silicon. In 2006, SiOnyx met with Hamamatsu, which produces silicon-based photodetector devices. The parties entered into a nondisclosure agreement (NDA), providing that a party receiving confidential information shall maintain the information in strict confidence for seven years after the expiration of the agreement and acknowledges that the disclosing party claims ownership of the information and all patent rights. While the NDA was in effect, SiOnyx provided to Hamamatsu proposed architectures and a manufacturing process for a photodetector device, which were marked as confidential. Hamamatsu ultimately represented that it wished to develop its products alone. The NDA expired in 2008. In 2009, Hamamatsu notified SiOnyx that Hamamatsu intended to introduce a new photodiode that it did not believe infringed SiOnyx’s intellectual property or breached Hamamatsu’s confidentiality obligations. Hamamatsu filed patent applications in several countries. In 2010, Hamamatsu began releasing the accused products. SiOnyx began selling its own photodetector products. In 2014 a customer alerted SiOnyx to Hamamatsu’s patents. The Federal Circuit affirmed that Hamamatsu breached the NDA and infringed the 467 patent. SiOnyx is entitled to sole ownership of the disputed U.S. Patents. The district court erred in failing to grant SiOnyx sole ownership of the Disputed Foreign Patents.
