Datatern Inc. vs. Sun Microsystems Inc. et al ('502 Patent)
Datatern Inc. vs. Sun Microsystems Inc. et al ('402 Patent)
Plaintiff Datatern, a Texas corporation, has filed two lawsuits against the same five defendants for alleged infringements of two of its patents.
In the first suit, Datatern claims it is the owner of U.S. Patent No. 6,101,502 issued Aug. 8, 2000, for an Object Model Mapping and Runtime Engine for Employing Relational Database with Object Oriented Software.
According to the original complaint, defendant Sun has had actual knowledge of the '502 Patent since at least Jan. 25, 2007, because on that date Sun requested an ex-parte re-examination of the patent with the U.S. Patent and Trademark Office.
Datatern alleges that Sun infringes the '502 Patent by making, using or selling software such as TopLink Essentials and induces others to infringe the patent by requiring compliance with its Java Persistence API portion of JSR 220: Enterprise JavaBeans, Version 3.0.
The plaintiff claims that Sun's willful infringement of the '502 Patent is demonstrated by public admissions made by Sun's general counsel, Mike Dillon.
"For example, Dillon spoke publicly about the 'breadth of the ('502) patent and the likelihood that it would be asserted against others,'" the suit states. Further, Dillon stated that Sun had decided to "invest the time and resources into a prior art search."
Defendants CollabNet, O'Reilly Media, Oracle and BEA Systems are directly infringing or indirectly infringing by inducing or contributing to the infringement. Products that allegedly infringe include TopLink Essentials, Oracle TopLink, BEA Kodo, Eclipse Link, Oracle Fushion Middle Ware and BEA Weblogic Server.
In the second suit, Datatern is defending its claims of U.S. Patent No. 5,937,402, issued Aug. 10, 1999, for a System for Enabling Access to a Relational Database from an Object Oriented Program. The suit alleges similar claims of infringements against the same defendants.
As a result of the infringement, Datatern claims it has suffered monetary damages in an amount not yet determined.
Datatern is seeking injunctive relief, compensatory and enhanced damages, interest, costs, expenses, attorneys' fees and other relief.
Daniel Perez of Dallas, Andrew Spangler of Longview and Patrick Anderson of Flint, Mich., are representing the plaintiff.

"On information and belief, defendant knows and intends that the fabric refresher products that defendant sells to its customers are sold by those customers to consumers to use for reducing malodors on inanimate surfaces," the complaint states.
P&G claims it has been damaged, in an amount yet to be determined, by defendant's acts of infringement and will continue to be damaged by such acts in the future.
