Tuam Tshoj Dental-Material Maker Wins Patent Case nyob rau hauv lub teb chaws Yelemees, tsoo Overseas Zirconia Patent Barriers

Lub hauv paus chaw nyob hauv Liechtenstein, Ivoclar Vivadent yog lub ntiaj teb kev lag luam kev kho hniav Thaum kawg ntawm Lub Ob Hlis 2026, Lub Tsev Hais Plaub Hauv Cheeb Tsam ntawm Düsseldorf tau xa thawj qhov kev txiav txim hauv qhov kev tsis sib haum xeeb ntawm patent-infringement ntawm Shanghai Huliang Biological Technology Co., Ltd. Lub tsev hais plaub tau tso tseg tag nrho cov lus thov xa los ntawm Ivoclar Vivadent.

Kev txiav txim siab tau lees paub tias Shanghai Huliang ntau txheej zirconia milling blanks nrog gingiva ntxoov ntxoo tsis poob rau hauv kev tiv thaiv ntawm ob European patents (EP3064170, EP3597143) tuav los ntawm tus neeg foob. Shanghai Huliang muaj cai txuas ntxiv xa tawm thiab muag nws cov gingiva-xim ntau txheej zirconia blanks hauv German khw. Cov ntaub ntawv kho dua tshiab, tuav cov ntaub ntawv tseem ceeb patents npog zirconia, lithium disilicate, kho hniav cob thiab lwm yam ntaub ntawv. Hauv qhov kev sib foob no, Ivoclar Vivadent liam tias Shanghai Huliang ntau txheej zirconia blanks nrog liab gingiva-simulating khaubncaws sab nraud povtseg ua txhaum nws European patents hais txog cov qauv thiab txheej txheej txheej txheem ntawm ntau txheej hniav ceramic blanks, thiab nrhiav ib lub tsev hais plaub injunction los thaiv cov Suav ua lag luam zirconia tag nrho cov ntaub ntawv.

Multi-layer zirconia blanks yog cov ntaub ntawv tseem ceeb rau kev tsim kho hniav digital. Cov pa monolithic zirconia tsuas tuaj yeem xa cov xim txhuam hniav. Multi-layer zirconia txais gradient xim thiab translucency qauv los simulate lub ntuj hloov ntawm dentin rau enamel. Zirconia blanks nrog gingiva ntxoov ntxoo yog embedded nrog ntxiv liab gingiva-mimicking khaubncaws sab nraud povtseg, muaj feem xyuam rau high-end restorations xws li PFM txuas hniav nrog cov pos hniav ceramic thiab monolithic zirconia All-on-6 full-arch implant txuas hniav rau cov neeg mob los ntawm alveolar pob txha resorption. Cov khoom lag luam no nyiam qhov kev thov nce thoob plaws Europe thiab Middle East. Nyob rau lub sijhawm ntev, cov neeg muab khoom siv txawv teb chaws monopolized lub lag luam high-end ntawm patents, teeb tsa cov kev txawj ntse thiab kev txawj ntse-cov khoom muaj nqis los txwv kev nkag mus rau kev lag luam ntawm Suav cov khoom sib tw.

Tom qab cov ntaub ntawv pov thawj hla kev tshuaj xyuas, kev sib piv cov txheej txheem thiab lub rooj sib hais hauv tsev hais plaub, Lub Tsev Hais Plaub Hauv Cheeb Tsam ntawm Düsseldorf tau tuav tias Ivoclar Vivadent ua tsis tiav cov ntaub ntawv pov thawj txaus ua pov thawj tias Shanghai Huliang cov khoom lag luam npog tag nrho cov txheej txheem kev sau tseg hauv daim ntawv thov patent. Shanghai Huliang tau txais kev ywj pheej-tsim txoj hauv kev raws li cov txheej txheem txheej txheem, cov khoom siv raw thiab cov txheej txheem sintering, uas txawv ntawm cov kev daws teeb meem tiv thaiv los ntawm patents hauv nqe lus nug. Yog li ntawd, cov ntaub ntawv ua txhaum cai raug tsis lees paub.

Nws yuav tsum raug sau tseg tias qhov no tsuas yog qhov kev txiav txim thawj zaug xwb. Ivoclar Vivadent tseem muaj txoj cai rov hais dua mus rau lub tsev hais plaub German siab dua nyob rau lub sijhawm raug cai, yog li qhov kawg ntawm rooj plaub tseem tsis paub meej. Txawm li cas los xij, qhov kev txiav txim thawj zaug uas zoo tshaj plaws no ua rau muaj kev cuam tshuam txog kev txawj ntse-txoj cai. Nws yog thawj zaug yeej tau txais los ntawm Tuam Tshoj cov khoom siv kho hniav hauv lub tsev hais plaub German hauv zos hauv zirconia-blank-related patent tsis sib haum xeeb.

Cov ntaub ntawv no muaj qhov tseem ceeb tshaj plaws rau Tuam Tshoj txoj kev lag luam kho hniav tag nrho. Patent teeb meem tau ntev dhau los yog ib qho teeb meem loj tshaj plaws rau cov chaw kuaj hniav hauv Suav teb thiab cov chaw muag khoom tshawb fawb hauv European lag luam. Cov tuam txhab kev kho hniav thoob ntiaj teb nquag tshaj tawm cov lus foob patent hauv Tebchaws Europe, thiab lees txais cov ntawv foob thiab kev puas tsuaj loj los thaiv cov nqi sib tw suav cov khoom siv kho hniav los ntawm kev nkag mus rau EU ua lag luam thiab nyem qhov chaw rau cov tuam txhab tsim khoom hauv tsev. Tau ntsib nrog kev iab liam patent txawv teb chaws, ntau lub tuam txhab Suav yav dhau los tau xaiv kev sib hais haum lossis tso tseg lub hom phiaj kev lag luam. Los ntawm nquag teb rau qhov kev foob thiab yeej nrog cov pov thawj ntawm kev tshawb fawb ywj pheej thiab kev txhim kho, Shanghai Huliang tau ua tus qauv tseem ceeb rau cov phooj ywg hauv tsev los daws cov kev tsis sib haum xeeb ntawm kev txawj ntse hla ciam teb.

EU ua lub lag luam tseem ceeb rau kev kho hniav kho hniav siab. Tom qab kev siv MDR, kev ua lag luam-kev yuav tsum tau ua nruj dua, thaum kev lag luam xav tau ntau txheej thiab gingiva-shaded zirconia tseem loj hlob. Qhov kev txiav txim no ua rau Suav gingiva-coloured multi-layer zirconia blanks kom nkag mus rau German lag luam. Nws muab ntau cov khoom siv raw lwm txoj hauv kev rau Suav kho hniav-outsourcing labs tsim All-on-6 zirconia txuas hniav thiab cov pos hniav-ceramic-txhim kho rau cov neeg European, pab txiav cov nqi raw khoom ntawm Tuam Tshoj txoj kev kho hniav-outsourcing sector, thiab txhim kho tag nrho cov kev sib tw ntawm Suav kho hniav prosthetics nyob teb chaws Europe.

Cov kws tshaj lij kev lag luam taw qhia tias nrog kev txhim kho txuas ntxiv hauv R & D muaj peev xwm ntawm Suav cov ntaub ntawv kho hniav, kev sib tw patent ntawm cov tuam txhab tsim khoom hauv tsev thiab cov tuam txhab loj hauv ntiaj teb yuav dhau los ua ntau dua thoob ntiaj teb. Thaum mus thoob ntiaj teb, sib nrug los ntawm cov khoom pov thawj thiab kev lis kev cai ua raws li kev lag luam, Suav cov tuam txhab kho hniav yuav tsum tau ua cov txheej txheem patent txawv teb chaws ua ntej, tsim kev txawj ntse-kev pheej hmoo-kev ceeb toom mechanisms, paub txog cov cai txiav txim ntawm lub hom phiaj kev lag luam, thiab teb rau cov lus iab liam patent los tiv thaiv cov cai thiab kev txaus siab.
