Sisvel tau tshaj tawm txog kev tsim lub pas dej patent npog cov thev naus laus zis uas sib tshooj nrog cov qauv pub dawb AV1 thiab VP9 video encoding. Sisvel tshwj xeeb hauv kev tswj cov cuab yeej cuab tam, sau cov nuj nqis thiab ua ntaub ntawv foob patent (patent troll, vim nws cov dej num kev faib tawm ntawm OpenMoko tsim yuav tsum raug ncua ib ntus).
Txawm hais tias AV1 thiab VP9 hom ntawv tsis tas yuav tsum muaj patent royalties, Sisvel tab tom qhia nws tus kheej cov ntawv tso cai, raws li cov tuam txhab tsim khoom txhawb nqa AV1 yuav tau them 32 eurocents rau txhua lub cuab yeej nrog lub vijtsam thiab 11 eurocents rau txhua lub cuab yeej tsis muaj lub vijtsam (rau VP9 tus nqi vaj tse tau txiav txim siab ntawm 24 thiab 8 euro xees, feem). Lawv npaj yuav sau cov nuj nqis los ntawm txhua yam khoom siv uas encode thiab txiav txim siab video hauv AV1 thiab VP9 hom.
Nyob rau hauv thawj theem, qhov kev txaus siab tseem ceeb yuav muaj feem xyuam nrog kev sau cov nuj nqis los ntawm cov tuam txhab ntawm cov xov tooj ntawm tes, TVs ntse, cov thawv teeb tsa, multimedia chaw thiab cov khoos phis tawj ntawm tus kheej. Nyob rau hauv lub neej yav tom ntej, kev sau cov nuj nqis los ntawm software encoder developers yuav tsis raug txiav tawm. Nyob rau tib lub sijhawm, cov ntsiab lus nws tus kheej hauv AV1 thiab VP9 cov qauv, cov kev pabcuam khaws cia thiab xa cov ntsiab lus, nrog rau cov chips thiab cov khoom siv kos duab siv hauv cov txheej txheem ua cov ntsiab lus yuav tsis raug rau cov nuj nqis.
Sisvel patent pool suav nrog patents los ntawm JVC Kenwood, NTT, Orange SA, Philips thiab Toshiba, uas kuj koom nrog MPEG-LA patent pas dej ua ke tsim los sau cov nuj nqis los ntawm kev siv AVC, DASH thiab HEVC hom. Daim ntawv teev npe patents suav nrog hauv cov pas dej patent cuam tshuam nrog AV1 thiab VP9 tseem tsis tau tshaj tawm, tab sis nws tau cog lus tias yuav luam tawm ntawm daim ntawv tso cai lub vev xaib yav tom ntej. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias Sisvel tsis muaj patents; nws tsuas yog tswj hwm patents ntawm peb tog.
Cia peb nco qab tias kom muab kev siv dawb ntawm AV1, Qhib Media Alliance tau tsim, uas tau koom nrog cov tuam txhab xws li Google, Microsoft, Apple, Mozilla, Facebook, Amazon, Intel, AMD, ARM, NVIDIA, Netflix thiab Hulu, uas. muab AV1 cov neeg siv nrog daim ntawv tso cai pub dawb siv nws cov patents uas sib tshooj nrog AV1.

Txoj kev tiv thaiv no tsis ua haujlwm tiv thaiv patent trolls xws li Sisvel, vim tias cov tuam txhab no tsis ua kev txhim kho lossis kev tsim khoom, thiab nws tsis tuaj yeem foob lawv hauv kev teb.
Hauv xyoo 2011, qhov xwm txheej zoo sib xws tau pom: MPEG LA tau sim tsim lub pas dej patent los sau cov nuj nqis rau VP8 codec, uas tseem muaj nyob rau hauv kev siv dawb. Lub sijhawm ntawd, Google muaj peev xwm ua tau raws li kev pom zoo nrog MPEG LA thiab tau txais txoj cai los siv rau pej xeem thiab tsis muaj nuj nqis patents uas yog MPEG LA npog VP8.
