Apple and Motorola could renew a patent case against one another after the US Court of Appeals ruled that a judge was wrong to throw out the original case in 2012.
The decision could have huge repercussions for both firms and Samsung, which is embroiled in a major legal battle with Apple in the courts of California.
The original ruling in 2012 by Judge Richard Posner said that Apple and Motorola's call for a sales ban against each others devices would be "catastrophic" for consumers.
Instead he said the firms should look to license their patents for use in each others devices. However, on Friday the US Court of Appeals disagreed with this ruling, paving the way for the firms to renew their litigation.
The decision came on the same day that Apple and Samsung presented their final arguments in the latest round of their long running patent saga. The jury for the case is expected to begin deliberations next week.
The ruling from the US Court of Appeals could have thrown a spanner in the works on the case, by opening up another patent for Apple to potentially use against Samsung. However, according to a report on Recode it appears neither firm moved to use the ruling in their final arguments.
Patent battles in the tech sector have been ongoing for several years now as rivals seeks to harm one another by attempting to have devices banned from sale.
However, some firms are now signing deals to avoid the threat of litigation. Cisco, Samsung and Google have all signed such deals with one another, while Microsoft and Motorola Solutions recently inked a deal to cover the latter's use of Android and Chrome.
