2012 年 11 月 13 日,一家設立於美國密蘇里州、以提供車速偵測與交通監控之技術服務的公司 B & W Sensors LLC ( 下稱 B & W Sensors) ,向美國密蘇里州東區聯邦地院提起確認之訴,請求法院就被告 American Traffic Solutions, Inc.( 下稱 ATS) 所宣稱擁有權利、並據以對 B & W Sensors 主張權利之兩項透過行車監控攝影機偵測行車速率的專利,做出專利無效與其權利未被 B & W Sensors 侵犯的宣告裁決 (declaratory judgment) 。

本案兩項系爭專利分別為美國專利編號 US 8,184,863 以及 US 8,213,685 ,名稱均為 「視訊速度偵測系統( Video speed detection system ) 」,發明人為 Jigang Wang ,前者於 2012 年 5 月 22 日核發,後者則於 2012 年 7 月 3 日核發。

American Traffic Solutions, Inc. 公司 之營運總部設立於亞利桑那州,提供道路安全監控攝影機相關技術與商業解決方案的公司。根據本案訴狀, ATS 於 2012 年 10 月 17 日透過其律師與 B &W Sensors 取得聯繫,表達 B &W Sensors 之複數行車追蹤系統 (Multiple Vehicle Speed Tracking system, MVST) 侵犯本案兩項系爭專利的數項請求項,而後在 10 月 18 日, ATS 向德州東區聯邦地院提起專利侵權告訴,控告 MVST 系統侵權 (American Traffic Solutions, Inc. v. B& W Sensors LLC, 案號為 1:12-cv-00504-RC) 。 B & W Sensors 指陳, ATS 之前述動作讓其具備提起本案確認之訴的訴權。

最近,有些訴訟案以確認之訴提起,而且有增加之趨勢。當收到專利權人的警告信之後,可能被控侵權者可以考慮先提起專利確認之訴,化被動為主動,向法院提起以對該專利不構成侵權、專利無效或專利不可執行性為的確認之訴。先提起訴訟的好處之一是可以因為「先繫屬規定 (first filed) 」先選擇對自己較有利的管轄法院,還有進入訴訟時避免陷入惡意侵權之嫌疑。 (518 字;表 2)
