Northeastern University and a start-up firm say Google's distributed search technology infringes on their patent.Google has been sued by a university and a start-up company in the U.S. for allegedly infringing on a patented technology to run its online search service.
The suit was filed by Boston's Northeastern University and by Jarg, a private company in Waltham, Mass., that specializes in distributed search technologies and one of whose cofounders, Kenneth Baclawski, is an associate professor at Northeastern.
The suit accuses Google of using a distributed database technology developed by Baclawski in its online service. The lawsuit seeks a jury trial and an injunction to prevent Google from further infringing on the patent, as well as royalty payments and damages.
The patent describes a distributed database system that breaks search queries into fragments and distributes them to multiple computers in a network to get faster results. The patent was assigned to Northeastern University, which licensed it exclusively to Jarg, according to the lawsuit, filed last Tuesday with the U.S. District Court for the Eastern District of Texas.
"The invention relates to a distributed computer database system which includes a front end computer and a plurality of computer nodes interconnected by a network," the patent states. "The combination of computer nodes interconnected by the network operates as a search engine."
The patent, number 5,694,593, is dated Dec. 2, 1997, and can be viewed by searching the Web site of the U.S. Patent & Trademark Office.
Google also uses a distributed database system that breaks queries into multiple parts for faster processing, the lawsuit states. It notes that Google makes 99 percent of its revenue from search advertising, and that the success of its business depends partly on the speed of its search results.
Jarg learned of the alleged infringement from a Boston-area lawyer who thought Google's search technology resembled that covered by the patent, said Jarg's president, Michael Belanger, according to a reportin Saturday's Boston Globe newspaper. The lawyer's firm would not take up the case unless it was paid in advance, and it took Belanger two and a half years to find a company willing to pursue the case on a contingency basis, the Globe reported.
Google said it was aware of the complaint and considers it to be "without merit," according to the report. Neither Google nor the plaintiffs could not immediately be reached for comment Sunday.
The Marshall Division of the Texas district court, where the suit was filed, is seen as a friendly venue for patent litigators. Although none of the actors in the case are based there, the lawsuit argues it is an appropriate venue for the case because Google provides services there.
No trial date has been set. The next stage will be for Google to respond to the lawsuit and for the court to decide whether a trial is warranted.
Northeastern is a private university known for its cooperative education program, in which students do vocational work as part of their degree. Jarg develops an intellectual property suite called the Semantic Knowledge Indexing Platform, which it markets to life sciences and health care companies through a subsidiary, Semantx Life Sciences.
