SAN JOSE, Calif.—TiVo said it has filed yet another patent infringement lawsuit against Comcast.

Through its Rovi unit, the company said its latest federal complaint, filed in the Central District of California, covers patents related to “cloud and multi-room DVR features” offered by Comcast Xfinity pay TV set-tops and gateways.

TiVo didn’t specify which patent numbers were involved—or if any of the patents have already been subject to the company’s wide-ranging, seemingly endless legal quest to get Comcast to pay it technology licensing fees.

“We believe Comcast’s Xfinity X1 continues to infringe Rovi’s cloud and multi-room DVR patents—a vital component of home entertainment,” said Arvin Patel, executive VP and chief intellectual property officer at Rovi Corporation, in a statement.

“Litigation is always a last resort but we will continue to take every necessary legal action to ensure that Comcast fairly compensates Rovi for its use of our patented innovations,” Patel added. “We have a responsibility to our stakeholders, licensees and customers to protect our intellectual property.”

Think of TiVo’s latest filing as simply putting more logs on the fire.

TiVo has been somewhat transparent about its legal strategy. The company is seeking to create as much legal action against Comcast as possible, around as many patents as it can. The aim is to put pressure on Comcast to either eliminate X1 features, or pay licensing fees.

The dispute dates back to 2016, when Comcast stopped paying licensing fees to TiVo.

“Comcast itself has been forced to remove certain functionality from Xfinity X1 and has been subject to an exclusion order after the ITC found it had infringed Rovi’s valuable IP,” TiVo said in a statement. “We are optimistic that Comcast will come to the table and pay the appropriate licensing fees to ensure their customers receive the best home entertainment services and features available.”

“Rovi has in recent years deployed its increasingly obsolete patent portfolio in an unsuccessful litigation campaign seeking to charge Comcast and our customers for technology that Rovi did not invent," Comcast replied in its own statement. "Rovi launched this campaign in April 2016 by asserting infringement of 15 patents—14 of which have been held to be invalid and/or not infringed by Comcast, or have been withdrawn by Rovi. While we haven’t had an opportunity to review Rovi’s latest complaint, we will continue to defend ourselves against allegations we determine to be meritless.”

Notably, TiVo’s latest filing comes as attorney Ashok Ramani, a partner for the firm Davis Polk, was named among the top IP lawyers in California by the Daily Journal.

Among Ramani’s recent career highlights, according to the Daily Journal, was defending Comcast in an eight-patent suit filed earlier by TiVo in the Central District of California. 

In a move that will get TiVo out of the hardware-making business, the company announced that it has signed a “major” device manufacturer to serve as its direct-to-consumer box partner.

Tied in, this partner, yet unnamed, will also take over retail sales of TiVo products outside of TiVo.com, including outlets such as Amazon and Best Buy, Enrique Rodriguez, TiVo’s president and CEO, said Thursday on the company’s Q1 earnings call.

TiVo, he explained, won’t produce or contract directly for the manufacturing of TiVo’s retail devices, but will secure the volumes needed from its new partner for sales made via TiVo.com.

“In that sense, we’re acting as a distribution channel,” Rodriguez said. With respect to sales through other retail channels, “we’d be completely out of that transaction.”

For consumers, there will be no material change, as products will continue to be branded as TiVo and run the TiVo experience, he added.

TiVo has already made a similar move on its MSO partnership business, as its software and experience have been ported to devices made by Arris.

On the MSO front, TiVo has completely transitioned out of the hardware business, as Q1 was the last with MSO hardware revenue, as TiVo has completed fulfillment of orders made last year, Rodriguez said.

On the software front, Rodriguez reiterated that TiVo’s new platform, TiVo Experience 4, was released to the retail market in Q4 2017, and is becoming broadly available to MSO customers this quarter. In the MSO realm, TiVo is using that new platform to help partners embark on IPTV transitions and as a catalyst to migrate MSOs from legacy Rovi guides to the higher-end TiVo experience.

Service Electric Cable TV is already on board, as is RCN Corp., which will be the first to roll out an IPTV service using TiVo Experience 4 using an Android TV device. Mediacom Communications recently renewed and extended its deal with TiVo.

TiVo is also preparing to launch a new advertising product that provides sponsored, in-guide recommendation results for relevant programming. A mid-tier MSO with coverage across “multiple, large DMAs” is signed on to deploy this on mobile devices and set-top boxes, Rodriguez said.

That capability will be deployed within TiVo’s personalized content discovery suite, he added, noting that it enables TiVo’s anonymous viewership data to be matched with other anonymous first- and third-party information.

TiVo had no new detail to share about its ongoing exploration of alternatives aimed at driving shareholder value that could include M&A or taking the company private.

That process is ongoing, though TiVo expects to be ready to provide an update when it announced Q2 results, Rodriguez said.

There’s also no significant movement with respect to TiVo’s ongoing litigation with Comcast.

“Getting a license [with Comcast] remains one of our top priorities,” Rodriguez said, holding that he’s “confident” that Comcast will eventually come to terms.

TiVo posted Q1 revenues of $189.83 million, down 7.7% year-over-year, driven by drops in its legacy TiVo solutions IP licenses and hardware line items.

TiVo, which merged with Rovi in the fall of 2016, said it reached its goal of realizing $100 million in integration synergies, and expects to complete its extended goal of $110 million by the end of Q2.

SAN CARLOS, CALIF. & SAN JOSE, CALIF.—The Rovi Corporation has announced that it will acquire TiVo for $10.70 per share, or approximately $1.1 billion. The two companies will now combine with Rovi CEO Tom Carson keeping his position and Rovi adopting the TiVo company name.

Rovi and TiVo serve pay-TV operators both in the U.S. and abroad. The combination of the two companies is hoped to enhance global reach, reportedly adding 10 million TiVo households to Rovi’s current base of 18 million. The new company will operate in the consumer, consumer electronic, service provider and web-scale marketplaces.

In addition TiVo’s cross-device viewership data is expected to merge with Rovi’s analytics tools for targeting of media spending, advertising inventory yield and the creation of targeted advertising capabilities, according to Rovi.

The boards of both Rovi and TiVo have approved the transaction. TiVo and Rovi stockholders will look to approve the merger at special meetings. The companies expect the transaction to become fully approved in the third quarter of 2016.

“The combined capabilities of TiVo and Rovi place us in a tremendous position to extend services across platforms and to a customer base that includes traditional, over-the-top and emerging players across the globe,” said Carson in Rovi’s press release.
