Google chairman Eric Schmidt publicly criticized Apple for its patent lawsuits against HTC, Samsung and Motorola at a Google conference in Tokyo.

The lawsuits are generally seen as an Apple attack against rival smartphone platform Android, which now leads the smartphone market.

Perth Now reported that Schmidt said that Apple’s lawsuits claiming patent infringement are spurred by jealousy and anxiety over the growth of Google’s Android platform.

“The big news in the past year has been the explosion of Google Android handsets and this means our competitors are responding," Schmidt reportedly said. “Because they are not responding with innovation, they're responding with lawsuits. We have not done anything wrong and these lawsuits are just inspired by our success.”

Schmidt also said that Google will support HTC in its fight, echoing the company’s official statement after a U.S. International Trade Commission ruling Monday that HTC smartphones infringe on two Apple patents. HTC plans an appeal.

Google said that the patent ruling did not find that the Android system infringed on Apple’s patents.

“We are confident the Commission will ultimately agree with the ITC staff's finding that HTC does not violate any of Apple's patents. Litigation that attacks open-source products limits consumer choice, hurts the economy, and discourages innovation,” the company said in a statement.
