Microsoft Corporation ("Microsoft") filed suit against Corel Corporation and Corel Inc. (“Corel”) in the Northern District Court of California, seeking to recover damages and costs for patent infringement.

In the complaint, Microsoft alleges Corel willfully infringes a number of Microsoft utility and design patents.  In particular, Microsoft accuses Corel of infringing U.S. Patent Nos. 8,255,828 (“the ‘828 patent”); 7,703,036 (“the ‘036 patent”); 7,047,501 (“the ‘501 patent”); 5,715,415 (“the ‘415 patent”); 5,510,980 (“the ‘980 patent”); D550,237 (“the D‘237 patent”); D554,140 (“the D‘140 patent”); D564,532 (“the D‘532 patent”); and D570,865 (“the D‘865 patent”), all relating to aspects of graphical user interfaces ("GUIs") used in productivity software applications, such as Microsoft Office.

The four design patents forming the basis for part of the complaint are directed to "ornamental designs for parts of Microsoft user interfaces, including the Microsoft Ribbon" and, according to Microsoft, "Corel's advertising makes the copied Microsoft interfaces one of the central selling points of Corel's products:  'With a familiar Ribbon-style interface, Corel® Office looks like the office software you're used to, making it easy to get to work right away.'" 

Accused Corel products associated with the asserted design patents include CorelCAD 2014-2016 and Corel Home Office, which includes Corel Write, Corel Calculate, and Corel Show.

Robert Gordon Industries, Ltd. ("Robert Gordon”) filed a complaint for declaratory judgment of noninfringement against Thermos, LLC (“Thermos”) on November 18, 2015 in the U.S. District Court for the Eastern District of New York.  Meanwhile, Thermos filed its own patent infringement action against Robert Gordon in the U.S. District Court for the Northern District of Illinois Eastern Division, also on November 18, 2015.

According to Robert Gordon, the declaratory judgment action was filed as a result of Thermos' continued efforts “to extract a royalty payment under two Thermos patents; United States Patent No. D622,547 entitled 'Tumbler' ('the ‘547 patent') and United States Patent No. 8,348,078 entitled 'Leak Proof Drinking Lid With Pressure Relief' ('the ‘078 patent')," with regard to Robert Gordon’s Empire VM-57 Tumbler, despite Robert Gordon's willingness to discontinue this product and pay Thermos a $3,000.00 royalty (based on 5% of past sales).  Robert Gordon seeks a jury trial to obtain a declaratory judgment of non-infringement and invalidity of each of the aforementioned Thermos patents. 

For its part, Thermos asserted that Robert Gordon has "manufactured, imported, sold and/or offered for sale tumblers...in the United States that infringe the '547 patent," such as tumbler "SKU # VM-57 Silver" offered for sale on Robert Gordon's website.   

Shown below, from left to right, are patent illustrations corresponding to Thermos' '547 patent (tumbler) and '078 patent (lid) and an image showing Robert Gordon's accused Empire VM-57 tumbler (based on Exhibit B from Thermos' complaint), respectively.

The American Bar Association (ABA)’s Section of Intellectual Property Law (IPL) will be holding its 29th Annual Intellectual Property Law Conference on April 2-4, 2014, at the Crystal Gateway Marriott Hotel, in Arlington, VA.  Of interest, on April 3rd at 1:45, conference participants will be able to attend a workshop entitled “The Rise of Design Protection: From Spoons & Carpets to Smartphones & Cars.” The ABA-IPL published this summary for the workshop:

Design protection has recently taken the spotlight due to some high-profile, high-stakes cases. Join these panelists for a practitioner-focused overview of design rights, where they will look into: why design patents require a different perspective from utility patents; what the most successful approaches are in prosecuting and litigating design patents; whether the approach to design rights in the U.S. is different from other countries undergoing such a surge.
