Cisco has taken Huawei to task over what it claims was a misreporting of the facts of a legal case between the two firms in which the US network giant accused its Chinese rival of using its intellectual property in its products.
The case dates back to between 2003 and 2004 and was eventually ended with a confidential settlement between the two firms.
Cisco has taken umbrage at the fact that Charles Ding, Huawei corporate senior vice president and chief representative in the US, claimed publicly that the outcome of the case was that Cisco stood down over its allegations.
"Huawei provided our source code of our products to Cisco for review and the results were that there was not any infringement found and in the end Cisco withdrew the case," Ding is reported to have said, according to Cisco in a blog written on 1 October.
In response to these statements, Mark Chandler, general counsel at Cisco, called on Huawei to release the report that formed the basis of the settlement between the two firms, so the public could assess the claim.
As this has not happened, Chandler took advantage of the opportunity to address the issue himself, claiming Ding had given Cisco the legal right to publish excerpts of the findings by an independent expert on the case, in a blog written on Thursday.
He reported several of the key findings from the report, including the two below, that appear unequivocal that Huawei did indeed use Cisco's own patented technology in its products.
The section entitled "Comparison of Cisco STRCMP and Huawei's [code name redacted], came the following: "It must be concluded that Huawei misappropriated this code."
Also, in the section "Comments and White Space", it was reported: "The exactness of the comments and spacing not only indicate that Huawei has access to the Cisco code but that the Cisco code was electronically copied and inserted into [Huawei's]."
Chandler then called on Huawei to "demonstrate their purported transparent business practices and respect for intellectual property rights" by publishing the full report by the expert to make the case clear for all to see.
V3 contacted Huawei for comment on the comments from Cisco but had received no reply at the time of publication.
The timing of Cisco's highly public criticism of Huawei over the legal case between the two firms is well-timed.
It comes the same week a damning report into the firm, and Chinese counterpart ZTE, was published in the US urging firms not to use their services due to security concerns.
Cisco has already severed ties with ZTE since the report came to light.
