Soverain Software LLC is a Chicago-based software company which owns patents for its ecommerce technology products. The company has patents for digital shopping carts commonly used on e-commerce websites, such as Amazon.com. Soverain claims that its enterprise software product Transact has been in use for nearly 18 years, and has been used by over 1,000 customers in over 25 countries, including companies such as Time-Warner, AT&T, Sony, Disney, BusinessWeek and Reuters, although this claim is disputed. Soverain Software has been characterized as a patent troll. == Patent infringement lawsuits == On January 12, 2004, Soverain sued Amazon.com and Gap Inc. in the U.S. District Court for the Eastern District of Texas. Gap settled with Soverain in February 2005 under undisclosed terms. In August that year, Amazon settled the case for $40 million.〔(【引用サイトリンク】url=http://www.zdnet.com/news/amazon-pays-40-million-to-settle-patent-dispute/144171 )〕 One of the patents involved a shopping cart mechanism used for online shopping. In 2010, Soverain Software filed a suit against a number of e-commerce companies, including Nordstrom's, Macy's, Home Depot, Radioshack, Kohl's and Newegg alleging infringement of U.S. Patents No. , No. and No. which relate to the concept of a digital shopping cart, similar to the 2004 case. When the case went to court in 2010, all defendants except Newegg had settled. Initially Newegg was found to have infringed the patents in suit and Soverain was awarded a judgement of $2.5 million fine instead of the $34 million claimed by Soverain.〔 On January 22, 2013, the U.S. Court of Appeals for the Federal Circuit reversed the district court and invalidated claims from all three asserted patents as being obvious in view of the prior art. The judgment against Newegg was vacated.〔(In Soverain Software LLC v. Newegg Inc., No. 11-1009 (Fed. Cir. Jan. 22, 2013) )〕〔(【引用サイトリンク】url=http://www.bakerlaw.com/alerts/patent-watch-soverain-software-llc-v-newegg-inc-1-23-2013/ )〕〔(【引用サイトリンク】url=http://www.prnewswire.com/news-releases/soverain-patents-found-valid-and-infringed-101300749.html )〕 The ruling of invalidity put a stay on the remaining lawsuits in progress.〔(How Newegg crushed the “shopping cart” patent and saved online retail ), by Joe Mullin - Jan 27 2013, arstechnica.com〕 On October 16, 2013, Soverain filed a petition for a writ of certiorari in Soverain v. Newegg to request a hearing with the Supreme Court of the United States.〔 (【引用サイトリンク】 url=http://www.ipwatchdog.com/2013/10/21/news-notes-october-21-2013/id=45759/ ) 〕 Three amicus briefs were filed by i4i, Professor Eileen Herlihy and MDB Capital who supported Soverain's petition.〔 (【引用サイトリンク】 url=http://www.law360.com/technology/articles/489997/soverain-ruling-threatens-patent-system-high-court-told ) 〕 On January 13, 2014, The Supreme Court denied the petition.〔 (【引用サイトリンク】 url=http://www.bloomberg.com/news/2014-01-13/internet-patent-owner-loses-high-court-bid-to-revive-suit.html )〕〔(【引用サイトリンク】 url=http://www.supremecourt.gov/orders/courtorders/011314zor_f204.pdf )〕 On February 13, 2015 a US Court of appeals invalidated Soverain's previous victories over Avon and Victoria's Secret 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Soverain Software」の詳細全文を読む スポンサード リンク
