Apple and Amazon have failed to reach an agreement over a lawsuit related to Amazon’s use of the term “Appstore” for its Android app download service, Reuters reports.

According to court filings, a phone conversation between lawyers for both companies on 14 June and an all-day meeting – attended by Apple’s chief intellectual property attorney BJ Waltrous and Amazon’s assistant general counsel Andre De Vore — on 1 May failed to settle the trademark infringement case before the trial takes place on 19 August.

Apple is seeking to block Amazon from using ‘Appstore’ for its online Android app portal as it alleges it infringes its trademark and violates competition law. The case is filed with the US District Court of the Northern District of Oakland, California.

Amazon launched its service in March 2011 and has said it believes ‘app store’ is a generic term that Apple does not have exclusive rights to.

Apple’s claim that Amazon was guilty of false advertising with the use of ‘app store’ was rejected by a US judge in January. The judge wrote that the use of the “Appstore” name by Amazon cannot be taken as a representation that it is the same service as Apple’s App Store.

Apple accused Amazon of misusing the ‘app store’ term to gain developers for its Amazon Appstore for Android download service.
