‘Legendary’ Judge Alsup Featured in Strata-gee May Go ‘Inactive’ in 2025

May 29, 2025 by Ted Leave a Comment

Featured in Sonos v. Google Patent Dispute

Law360, a legal newsletter, reported on Tuesday that U.S. District Judge William H. Alsup – a judge in the Northern District of California – has filed papers with the court notifying it that he will likely take “inactive status” sometime in 2025. Calling him a “larger-than-life jurist” who has presided over some of the most consequential cases in America, Law360 says Judge Alsup is “legendary” in the U.S. legal system. I concur…

Judge Alsup was featured in one of Strata-gee’s most popular stories ever written on patent battles, this one between Sonos and Google. There was a remarkable twist at the end of this story based on real-world detective work by Judge Alsup.

U.S. ITC Launches Massive Investigation of Certain TVs, Remotes & Components

May 19, 2021 by Ted Leave a Comment

Broad Implications of Roku, Inc. v. Universal Electronics, Inc.

The U.S. International Trade Commission (ITC) has launched a massive investigation into a wide range of televisions, remote controls, and other components that is sure to rattle a few cages around the industry. The investigation is the result of a patent infringement action taken by Roku, Inc. (Roku) against Universal Electronics, Inc. (UEI) and a long list of UEI customers and associates back in April. At the same time that Roku filed their lawsuit in a California District Court, they also filed a complaint with the ITC alleging Section 337 violations (“unfair imports”) by the same long list of prominent players in electronics.

Sonos & Google Patent War Gets Ugly, Each Accuses the Other of Bad Faith

December 3, 2020 by Ted 2 Comments

A hearing before a California federal judge brought an ugly exchange between attorneys for both Sonos and Google – with each side pointing their finger at the other and accusing them of bad faith. That attorneys got ugly against their counterparts is not in itself surprising. However, the speed with which this dispute devolved to that point was a surprise.

Sonos Sues Google in Boldest Patent Action Yet

January 7, 2020 by Ted Leave a Comment

“When you strike at a king, you must kill him”…Ralph Waldo Emerson

Sonos announced on Tuesday that it has filed a patent infringement lawsuit against tech powerhouse Google – by far their biggest…and potentially riskiest…action yet. And perhaps keeping Emerson’s quote in mind, Sonos took a double punch at the king, filing a lawsuit against Google in the District Court for the Central District of California…AND at the same time, filing a complaint with the United States International Trade Commission. This is the first time, Sonos has started a war on two fronts, suggesting to me that they are deadly serious in this effort.

Giving No Ground, Lenbrook Launches Robust Retaliation to Sonos Lawsuit

October 20, 2019 by Ted Leave a Comment

After receiving a stipulation allowing them more time to respond, Lenbrook Industries Ltd, and Lenbrook America, last week filed their response to the Sonos patent litigation they were hit with in June. It was a robust and smart response that clearly communicated that Lenbrook planned to give no ground in this dispute.

While perhaps not quite as audacious as the D&M response when they were first dealt the blow of litigation…Lenbrook offered a smart and savvy response that not only pushed back but seemingly undercuts many of Sonos’ core allegations..and patents.

Sonos v Lenbrook is heating up…who has the advantage?…

Lenbrook Responds to Sonos Lawsuit, It Will ‘Defend Vigorously the Claims’

June 26, 2019 by Ted 4 Comments

Strata-gee reported yesterday that late last week Sonos had filed a patent infringement lawsuit against Lenbrook Industries Limited and Lenbrook America. This suit, which is almost identical to the one Sonos had successfully pursued with D&M Holdings and Denon over its HEOS line, was resolved in Sonos’s favor a little over a year ago.

Now we have Lenbrook’s response to this development – the company says it will “defend vigorously the claims of patent infringement made by computer audio company Sonos…”

See what else Lenbrook had to say about the Sonos suit…

First Time Ever: Asia Files Majority of Global Patents

Huawei Files the Most Individual Patents

Global competition continues to heat up and nowhere is that more obvious than a recent analysis from the World Intellectual Property Organization noting that in 2018 – for the first time in human history – the region of Asia filed the majority of all international patent applications. This new reality suggests that Asia is “rapidly increasing their presence in global innovation,” the report says.

And which company in particular was tops in the world for innovation? WIPO says it was Huawei Technologies, who filed the most patents from a single company in the world.

Sonos to Seek Injunction to Stop HEOS Sales of ‘Infringing Technology’

December 20, 2017 by Ted 14 Comments

BREAKING NEWS

Case May Have Major Impact on Wireless Speaker Business

As we recently reported, a federal jury gave Sonos a sweeping victory in the first “bellwether trial” in Sonos Inc. v. D&M Holdings Inc. et al, siding with Sonos on all counts and awarding them nearly $2 million in damages. Furthermore, the jury affirmed the validity of the three Sonos patents at issue, and disagreed with D&M’s assertion that the patents were not valid.

Strata-gee spoke with both sides of this case and, this decision notwithstanding, neither appears ready to back down, even as this is just the first of what will ultimately be three trials in the case – two where Sonos is the plaintiff, and a countersuit by D&M Holdings where they will be the plaintiff. Sonos won round one, but this is a multi-round fight.

Verdict: ‘Denon Directly Infringed’ on Sonos Patents

BREAKING NEWS

Jury Finds for Sonos on All Counts; Denon Claims of Invalidity Vanquished

Last Friday, after a full week of testimony, evidence, deposition playbacks, and attorney posturing, members of the jury listened closely as Judge William C. Bryson delivered instructions designed to clarify their deliberative process and their duty as “finders of fact” in the matter of Sonos, Inc. v. D&M Holdings Inc. d/b/a/The D+M Group, D&M Holdings U.S. Inc., and Denon Electronics (USA), LLC. The judges verbal instructions took a while to relay, as the reality is that patent disputes can be quite complex and the issues of intellectual property quite nuanced yet important.

In written form, which the Judge provided the jury for their easy referral, his instructions ran a full 27-pages long. After considering it all, the jury came back with a finding in favor of Sonos on all counts – and delivered an award to Sonos of just under $2 million for damages.
