Litigation Practice Results

Benchmark Technologies, Inc. v. Yuqiang (Richard) Tu and Kifonix Technology, LLC.

United States District Court for the District of Massachusetts

The U.S. District Court for the District of Massachusetts ruled in firm client Benchmark Technologies’ favor and denied defendants’ motion seeking to overturn the favorable jury verdict and final judgment in Benchmark Technologies, Inc. v. Yuqiang (Richard) Tu and Kifonix Technology, LLC. The Court’s order affirmed an earlier judgement after a 5-jury trial in January 2023, that Benchmark's claims, including trade secret and unfair competition claims.

Benchmark, an international supplier of test reticles, photomasks, and related services for lithography systems, filed suit in February 2022, after its former senior applications engineer resigned to form a competing business and, among other misconduct, misappropriated five categories of trade secrets — valuable Benchmark intellectual property that gives the company a distinct competitive advantage in the market.

With quick action, Sunstein was able to swiftly shut down the defendants’ illegal activity on Benchmark’s behalf with a temporary restraining order and preliminary injunction, protecting vital portions of Benchmark’s business from irreparable harm.


Trade Secret Victory

KPM Analytics North America Corp. v. Blue Sun Scientific LLC et al.

United States District Court of Massachusetts

Following a rigorous two week trial concerning theft of trade secrets owned by KPM Analytics, a supplier of near-infrared analyzers used for spectrographic analysis, a federal jury found in favor of KPM, finding its competitor guilty of trade secret misappropriation, unfair and deceptive trade practices, and contract breaches. The jury initially awarded $3.4 million in damages, and those damages were later enhanced by the court to $6.7 million.

In KPM Analytics North America Corp. v. Blue Sun Scientific LLC et al., KPM sued Blue Sun Scientific LLC and its parent company, The Innovative Technologies Group & Co., in April 2021 for poaching key personnel, customer data and proprietary software. In August 2021, the United States District Court entered a preliminary injunction against both companies and four of KPM’s former employees now working at Blue Sun.

The jury found that Blue Sun unlawfully used KPM trade secret information and that it and the four former KPM employees stole trade secrets and violated non-disclosure agreements and good faith covenants. The four former employees and both companies were ordered to pay separate damages based on the severity of their wrongdoing.


Trade Secret Victory

Ingenico Inc. v. IOENGINE, LLC

United States District Court of Delaware

Sunstein obtained a sweeping jury verdict win in a patent infringement lawsuit for Ingenico Inc., a global provider of point of sale payment terminals, software, and services. Sunstein also filed multiple petitions for inter partes review (IPR), successfully invalidating over 150 of the patent claims in IOENGINE’s three asserted patents.

The exhaustive discovery process included tens of thousands of documents, 20-plus depositions (including multiple depositions of third parties in Israel), and significant third-party discovery. Notably, Sunstein challenged the methodology by which IOENGINE’s damages expert calculated reasonable royalty damages, prompting the court to exclude the expert’s testimony. After four days of testimony, the jury found that all claims were either not infringed or were invalid.

Immersive Display Solutions, Inc., Strafe Services et al. adv. Fidelity Technologies Corporation et al.

United States District Court for the Eastern District of Pennsylvania

Representing the defendants, Sunstein defeated a hard fought motion for preliminary injunction brought by a rival technology company seeking to shut down our clients’ ability to work on a military training equipment project. Fidelity Technologies Corporation and Fidelity Technologies Middle East LLC filed the suit in January 2016 in the Eastern District of Pennsylvania, asserting theft of trade secrets, civil conspiracy, unjust enrichment, and unfair competition. Through swift action and marshalling of detailed information -- and after an extensive evidentiary hearing in Allentown, PA -- the Sunstein team defeated Fidelity’s motion for a preliminary injunction in just over a month after the complaint was filed.

Exergen Corporation vs. Kaz, USA, Inc.

United States District Court for the District of Massachusetts

Sunstein’s trial team won a jury verdict for our client Exergen, resulting in a $16 million judgment against Kaz, the maker of consumer products sold under the Vicks and Braun brands. Despite Kaz’s multiple challenges to the twelve patent claims asserted by Exergen, the jury upheld the validity of all of them, and found that the forehead thermometers sold by Kaz infringed those claims. Exergen is a Watertown, MA-based manufacturer and seller of thermometers for both the professional and consumer markets.


$16 million judgment

Softspikes, LLC et al. v. MacNeill Engineering Company, Inc. Trisport, Ltd. et al. v. MacNeill Engineering Company, Inc. et al.

United States District Court for the District of Delaware

In this pair of patent litigations, Sunstein defended MacNeill Engineering against claims of infringing five patents owned by related companies Softspikes and Trisport. In the first litigation Sunstein obtained favorable claim construction rulings that forced Softspikes to drop one of the two patents it had asserted against MacNeill. Faced with these setbacks and a counterclaim for infringement of three of MacNeill’s own patents with a substantial claim for damages, the plaintiffs agreed to a settlement and dismissed their cases.

FairWarning IP, LLC v. Iatric, Inc.; FairWarning IP, LLC v. CynergisTek, Inc.

We successfully defended clients Iatric and CynergisTek in the District Court and Federal Circuit against claims of patent infringement relating to software for detecting fraud and misuse of protected health information. Sunstein litigation group obtained judgments of patent invalidity under Section 101.

VLT Inc. v. Power-One, Inc

United States Court of Appeals for the Federal Circuit, United States District Court for the District of Massachusetts

Sunstein won the appeal for Power-One which upheld a judgment of non-infringement. We also represented Power-One in Federal District Court in Massachusetts in this patent infringement action, which concerned power converters essential for providing a DC voltage to computers or other electronic equipment. Early in the litigation, we forced the plaintiff to narrow its claim brought against hundreds of millions of dollars in sales down to the limited sales of a particular series of power converters, and next forced the plaintiff to drop its claims for lost profits. We then obtained favorable claim construction and judgment of non-infringement as to the remaining series of power converters.

Hambrecht Wine Group, L.P. d/b/a Belvedere Winery, L.P. v. Millennium Import LLC

United States District Court for the Northern District of California

Sunstein obtained a summary judgment ruling in favor of its client, a Sonoma winery, holding that the winery’s trademark licensee, an importer of luxury vodka, breached its license to use the BELVEDERE® trademark, that the winery properly terminated the vodka importer’s license, and, accordingly, that the importer’s continued sales of BELVEDERE® vodka infringed the winery’s trademark rights. The case, which was litigated in the federal court in San Jose, settled shortly after the summary judgment ruling.

M&M Label Company, Inc. v. Lone Peak Labeling Systems, Inc.

United States District Court for the District of Massachusetts

Sunstein brought suit in federal district court in Massachusetts against Lone Peak Labeling System on behalf of its client M&M Label Company in an action for breach of contract, trademark infringement, false designation of origin and unfair competition. M&M Label is a leader in the label, decal and nameplate production and printing industry in the United States and the creator of the proprietary label-printing system sold under the trademark THE MERCHANDISER. After seeking a preliminary injunction, we obtained an agreement from Lone Peak to, among other things, immediately cease use of the mark THE MERCHANDISER and to abandon its application with the USPTO.

AOL, LLC, Time Warner, Inc., et al. v. NameMedia, Inc.

United States District Court for the Eastern District of Virginia

Sunstein represented NameMedia in a federal court action in the Eastern District of Virginia “rocket docket” brought by AOL, Time Warner, and associated companies. Plaintiffs asserted claims including trademark infringement, cybersquatting, and breach of contract relating to the registration of certain domain names. After vigorous motion practice on numerous issues, including the successful defeat of plaintiffs’ motion to dismiss NameMedia’s reverse domain name hijacking counterclaim (an issue of first impression), and motion practice related to NameMedia’s defense that the agreement underlying AOL’s breach of contract claim was unenforceable due to conflict of interest, a stipulation of dismissal of the action, with prejudice, was entered.

First Act Inc. v. Brook Mays Music Company, Inc.

United States District Court for the District of Massachusetts

Sunstein won a $20.7 million jury verdict for First Act in this suit for false advertising in violation of the Lanham Act, commercial disparagement and interference with contractual relations. During the five-week trial, we presented extensive expert witness testimony including in-courtroom demonstrations as proof that defendant’s statements about our client’s musical instruments were false. The global aspects of the parties’ manufacture and distribution of the products in issue posed unique challenges involving discovery throughout the United States and in China and Hong Kong. In addition, because of the harm being caused to our client on an ongoing basis, we acted quickly upon filing suit to obtain expedited discovery and a preliminary injunction against the defendant. The case is also of general interest because we established jurisdiction in Massachusetts over the Texas-based defendant by proving (among other facts) the defendant’s contact with Massachusetts through email messages sent to residents of the forum state.

Ken’s Foods, Inc. v. Ken’s Steak House, Inc.

United States District Court for the District of Massachusetts

Sage Naturals promoted use of its medical marijuana products to treat the same types of CNS disorders that Sage Therapeutics’ investigational medicines were intended to treat.
