6.專利價(jià)值分析

Innography將近十年美國(guó)授權(quán)專利各指標(biāo)的平均數(shù)值作為評(píng)價(jià)標(biāo)準(zhǔn),歸一化后繪制成雷達(dá)圖。下圖中右側(cè)圖例中的數(shù)據(jù)即為各項(xiàng)指標(biāo)的標(biāo)準(zhǔn)數(shù)值,在雷達(dá)圖中以數(shù)值為1表示。

從圖中可以看到豐田汽車與燃料電池相關(guān)的專利在訴訟、專利引用上遠(yuǎn)低于平均值,說(shuō)明豐田汽車的專利訴訟較少且專利原創(chuàng)度較高,通過(guò)借鑒或合作進(jìn)行的創(chuàng)新較少。豐田汽車專利的發(fā)明人高于平均值,說(shuō)明其發(fā)明團(tuán)隊(duì)較大。

豐田汽車在燃料電池汽車的研發(fā)進(jìn)展及專利分析

圖8 專利價(jià)值分析  數(shù)據(jù)來(lái)源:Innography.com

下圖顯示,豐田汽車與燃料電池相關(guān)的專利總量為15867件,其中,10782件專利是有效的,包括5373件有效授權(quán)和5409件有效申請(qǐng)。豐田汽車失效專利數(shù)量較少,僅為5085件,占專利總量的32%。

圖9 專利有效性 數(shù)據(jù)來(lái)源:Innography.com

Innography專利強(qiáng)度指標(biāo)參考了10余個(gè)專利價(jià)值的相關(guān)指標(biāo),包括:專利權(quán)利要求數(shù)量、引用先前技術(shù)文獻(xiàn)數(shù)量、專利被引用次數(shù)、專利及專利申請(qǐng)案的家族、專利申請(qǐng)時(shí)程、專利年齡、專利訴訟等,如果一件專利強(qiáng)度越高,可以確定該專利的質(zhì)量和影響力越高。

對(duì)豐田汽車的所有與燃料電池相關(guān)的專利族進(jìn)行專利強(qiáng)度分析,發(fā)現(xiàn)其專利強(qiáng)度超過(guò)90的專利有88件,涉及氫燃料電池控制系統(tǒng)、燃料電池堆、冷卻裝置、燃料電池制造等。88件專利全部有效,僅有3件專利將在2020年前失效。
