A storied but rapidly-shrinking intellectual-property-law boutique, Kenyon & Kenyon LLP, is moving its practice to full-service Texas law firm Andrews Kurth LLP, marking the latest closure from a shrinking national roster of intellectual-property-law firms.

The deal, to be finalized in the coming days, comes after months of defections from New York-based Kenyon, which counts companies including Mattel Inc., Sony Corp. and Volkswagen AG as clients. The firm employed more than 200 lawyers a decade ago but is down to 55 today in New York, Washington, D.C., and Palo Alto, Calif. All are joining Andrews Kurth, a 350-lawyer firm that focuses on the energy, finance and technology sectors.

Founded in 1879, Kenyon is the latest in a string of old-line intellectual-property-law firms to close over the past several years. Like Kenyon, many have been absorbed into full-service firms, largely a reflection of the increasing importance companies now place on the protection of patents, trademarks and copyrights.

"We always invented things, but high-tech turns on intellectual property," said legal consultant Aric Press. Starting around the late 1990s, he said, "patents became litigated over with no holds barred and no budgets," turning intellectual property into a lucrative and coveted practice for larger firms.

Intellectual-property lawyers—both litigators and those who process patent applications—typically have technical backgrounds, with many holding advanced degrees in engineering or the sciences. That has made poaching existing intellectual-property specialists or scooping up entire boutiques even more attractive to larger firms trying to get into the practice.

In 2005, for instance, Ropes & Gray LLP acquired then-prominent intellectual-property firm Fish & Neave. By then, two other stalwarts in the field, New York's Pennie & Edmonds and Los Angeles-based Lyon & Lyon LLP, had both gone bust, with lawyers decamping to other firms. Several smaller intellectual-property firms have been acquired or dissolved more recently, including Morgan & Finnegan LLP, whose lawyers joined Locke Lord LLP in 2009.

Some intellectual-property firms have been able to stay independent by growing larger themselves, like 370-lawyer Fish & Richardson, 280-lawyer Knobbe, Martens, Olson & Bear LLP and Finnegan, Henderson, Farabow, Garrett & Dunner LLP, with 350 professionals.

Steven Nataupsky, managing partner of Orange County, Calif.-based Knobbe, said he thinks stand-alone intellectual-property firms can survive by being large enough to employ experts in a range of technical industries and by keeping a mix of litigators and those who help companies apply for patents.

"I think those midsize (intellectual-property) firms, if not balanced, have really struggled," he said.

Andrews Kurth managing partner Robert Jewell said his firm had been looking to add intellectual-property lawyers to its current roster of 33 as part of its focus on technology.

Rather than a merger, the deal is structured in a way that has become popular lately: hire the lawyers but leave the struggling firm's liabilities behind. Kenyon managing partner Edward Colbert said the shell of Kenyon would be wound down.

Mr. Colbert said Kenyon, which has helped protect patents for inventions ranging from the electric trolley and rechargeable batteries to windshield wipers and videogame consoles, has weathered multiple swings in the market but could no longer go it alone.

He said the firm had been affected by some of the latest hits to patent work, including 2011's America Invents Act, which created a new method for adjudicating some patent disputes, and a 2014 U.S. Supreme Court decision that limited patents on abstract concepts, including software and business methods.

Mr. Colbert has been public about his firm's uncertain future for several months. He said Monday that since late last year he has fielded at least a pitch a week for a combination, and that conversations with Andrews Kurth began about eight months ago.

Despite recent troubles, Kenyon's work has continued to involve household names. In October a judge sided with a travel website represented by Kenyon in a trial over whether the company infringed on social-media giant Pinterest Inc.'s rights to the term "pin." The firm has long advised the U.S. Olympic Committee and advised John Oliver, host of HBO's "Last Week Tonight," in trying to trademark the term "Drumpf" in relation to Donald Trump's run for the presidency.

The combination with Andrews Kurth won't completely relegate the Kenyon name to the history books. In New York, Washington D.C. and California, and in the branding of the intellectual-property practice, the firm will now be known as Andrews Kurth Kenyon.
