Microsoft’s online payment platform, PGE (Payment Gateway), and IBM (IBM Payments) are among the companies that have faced antitrust investigations over allegations that they may have favored certain companies in bidding for market share.
In a joint complaint filed Monday in federal court in New York, Microsoft and IBM alleged that PGE had failed to comply with antitrust rules on price-fixing and anticompetitive conduct and violated antitrust laws by using its market power to help certain companies win market share in the online payments market.
The companies also allege that IBM did not pay the minimum wage required by antitrust law and violated labor laws by not providing full-time employees with sick leave or paid leave.
“We believe that Pge has an obligation to its customers to provide them with fair and equitable compensation,” said a Microsoft spokesperson in a statement.
IBM declined to comment on the lawsuit.
Microsoft is the largest cloud computing vendor, with revenue of about $10 billion in 2016.
Microsoft bought PGE in 2014 for about $1 billion, but has been losing market share to Amazon.com, which has recently begun to aggressively target its online payments business, and to Google, which recently announced a partnership with PayPal.
The new antitrust complaint alleges that PGe failed to disclose its market dominance in the industry as early as 2010, a violation of antitrust rules.
The complaint, which names Microsoft as a defendant, names Microsoft, IBM and Amazon, as well as other cloud computing providers.
The company said in a separate statement that it is reviewing the complaint.
Microsoft has been the subject of several lawsuits alleging antitrust violations since 2012.
Microsoft was among the largest pay-per-use providers when the law was enacted in 1996, and its cloud-based payments service was the dominant platform for online payments until Amazon, which announced a deal in November, emerged as a strong competitor.
Amazon’s move has raised questions about the extent to which pay-based payment platforms will survive in the new marketplace.
IBM has also faced a series of lawsuits in recent years alleging unfair business practices, and IBM has been sued for anticompetition violations by PGE.
In 2014, a judge ruled in favor of IBM, finding that IBM’s payment technology did not deliver the same level of service as PGE’s payment platform.
IBM said in February that it would stop using PGE and pay-for-performance payments from 2018.
The case was filed in U.S. District Court for the Southern District of New York.
