Submit a Patent

Any entity believing it has a valid patent essential to a normative part of the MPEG-4 Scalable Lossless Coding Standard, specifically ISO/IEC 14496-3:2009 “Information Technology—Coding of audio-visual objects—Part 3: Audio”, Subpart 12, Scalable Lossless Coding (“SLS Standard”).

Patents are considered essential when they are determined to have at least one independent claim that would be necessarily and unavoidably infringed (in the absence of a license) by the practice of the SLS Standard.

An evaluation fee of US $10,000 must accompany the submission of each patent, the patent's prosecution history, and copies of all references relied upon by the examining patent office. In addition, an initial submission must be accompanied by a signed letter indicating agreement with the terms and conditions governing the patent submission process.

If informed by the Independent Patent Evaluator that the submitted patent is essential to the SLS Standard, the submitter is expected to participate in the SLS Licensing Committee and the patent licensing program. Such participation will require the payment of a membership fee to help defray the shared costs of the Licensing Committee.

Please contact Via Licensing at to request a copy of the letter describing the submission procedures and the terms and conditions governing the submission of patents for essentiality determination in order to join the SLS licensing program.
