Sisvel yalengeza za kupanga matekinoloje a patent dziwe omwe amalumikizana ndi mawonekedwe aulere a AV1 ndi VP9 encoding. Sisvel imagwira ntchito pa kasamalidwe ka zinthu zaluntha, kusonkhanitsa ndalama zaulemu ndikulemba milandu ya patent (patent troll, chifukwa cha zomwe ntchito yake yogawa OpenMoko inayenera kuyimitsidwa kwakanthawi).
Ngakhale mawonekedwe a AV1 ndi VP9 safuna malipiro a patent, Sisvel ikuyambitsa pulogalamu yakeyake, pomwe opanga zida zothandizira AV1 azilipira ma euro 32 pachida chilichonse chokhala ndi skrini ndi ma euro 11 pachida chilichonse popanda chophimba VP9 ndalama zachifumu zomwe zimafotokozedwa pa 24 ndi 8 euro senti, motsatana). Akukonzekera kutolera ndalama kuchokera pazida zilizonse zomwe zimasunga ndikusintha makanema mumitundu ya AV1 ndi VP9.
Pa gawo loyamba, chidwi chachikulu chidzakhala chokhudzana ndi kusonkhanitsa ndalama kuchokera kwa opanga mafoni a m'manja, ma TV anzeru, mabokosi apamwamba, ma multimedia malo ndi makompyuta aumwini. M'tsogolomu, kusonkhanitsa ndalama kuchokera kwa opanga makina osindikizira sikungalephereke. Nthawi yomweyo, zomwe zili mumitundu ya AV1 ndi VP9, ββntchito zosunga ndi kutumiza zomwe zili, komanso tchipisi ndi ma module ophatikizidwa omwe amagwiritsidwa ntchito pokonza zomwe zili mkati sizikhala ndi malipiro.
Phukusi la patent la Sisvel limaphatikizapo ma patent ochokera ku JVC Kenwood, NTT, Orange SA, Philips ndi Toshiba, omwe amatenga nawo gawo mu maiwe a patent a MPEG-LA omwe adapangidwa kuti atolere zaulemu kuchokera pakukhazikitsa mawonekedwe a AVC, DASH ndi HEVC. Mndandanda wa ma patent omwe akuphatikizidwa m'madziwe a patent omwe amagwirizana ndi AV1 ndi VP9 sanawululidwebe, koma alonjezedwa kuti adzasindikizidwa patsamba la pulogalamu yopereka chilolezo mtsogolomo. Ndikofunikira kudziwa kuti Sisvel alibe ma patent, amangoyang'anira ma patent a anthu ena.
Tiyeni tikumbukire kuti kuti tipereke kugwiritsa ntchito kwaulere kwa AV1, Open Media Alliance idapangidwa, yomwe idalumikizidwa ndi makampani monga Google, Microsoft, Apple, Mozilla, Facebook, Amazon, Intel, AMD, ARM, NVIDIA, Netflix ndi Hulu, omwe. idapatsa ogwiritsa ntchito AV1 chilolezo chogwiritsa ntchito mwaulere ma patent ake omwe amapitilira ndi AV1. Mfundo za mgwirizano wa laisensi ya AV1 zimaperekanso kuthetsedwa kwa ufulu wogwiritsa ntchito AV1 ngati zonena za patent ziperekedwa kwa ogwiritsa ntchito ena a AV1, i.e. makampani sangagwiritse ntchito AV1 ngati akukhudzidwa ndi milandu yotsutsana ndi ogwiritsa ntchito AV1. Njira yodzitetezera iyi sigwira ntchito motsutsana ndi ma patent trolls monga Sisvel, popeza makampani oterowo sachita ntchito zachitukuko kapena kupanga, ndipo ndizosatheka kuwasumira poyankha.
Mu 2011, zinthu ngati izi zidawonedwa: MPEG LA idayesa kupanga dziwe la patent kuti litolere ndalama za VP8 codec, yomwe imayikidwanso kuti igwiritsidwe ntchito kwaulere. Panthawiyo, Google idakwanitsa kuchita mgwirizano ndi MPEG LA ndipo idapeza ufulu wogwiritsa ntchito poyera komanso ma patent aulere a MPEG LA omwe amakhudza VP8.
