針對Patent Troll的問題，美國國會眾議員Mr. DeFazio在2013年2月重新提出了其在2012年提過的SHIELD (Saving High-Tech Innovators from Egregious Legal Disputes Act of
2013) 法案。這個2013年的版本跟2012年的版本很不一樣。如果您對SHIELD法案內容的認知還停留在那個問題很多的2012年版，那麼您可能要重新看一下了。
這個版本的重點，是定義了 "非patent troll" 的三種實體：
- 原始發明人，這包括原始的受讓人；
- 利用專利的人，即有實質投資以生產或銷售專利權所涵蓋的產品的人；以及
- 大學與技轉組織，即符合20 U.S.C. 1001第101條定義的實體，以及為這種實體的技術進行商業化的技術移轉組織。
如果不符合這三種實體的任何一種，那麼在專利訴訟中，主張專利無效或不侵權的當事人，就可以聲請法院裁定如果其勝訴，對造應負擔其律師費。此外，法院也應要求該對造提供擔保，金額由法院決定。
這個版本還是有很多問題。比如，所謂 “exploitation of the
patent through production or sale of an item covered by the patent”，由於理論上只有在美國製造或販賣的產品，才有被美國專利涵蓋的可能，所以一家公司如果買來一個在台灣、大陸與美國取得專利的專利家族，然後只在台灣與大陸製造或販賣相關產品，那麼它在美國主張專利權時，很可能會被認定為並非是利用專利的人 (他沒有在美國利用“美國”專利)。由於它也不是原始受讓人或大學技轉組織，它在美國就變成patent troll了。
然而，那個在美國的被告，可能在美國製造後，產品賣到大陸去與原告競爭。專利權人只因為沒有在美國製造與販賣，它在美國訴訟就必須押擔保金，並且在敗訴後負擔對方律師費。這似乎不太合理。
這邊所謂 “ exploitation”
，在著名的美國關稅法第337條，也有類似的用語，而且之前還爭執過這個用語的意義 (比如這個案子，從第7頁開始)。所以 “ exploitation”
應該如何解釋，值得注意。
此外，"非patent troll" 的三種實體似乎不包括研究機構，也不確定是否包括海外的大學。如果真的都不包括，那麼比如台灣的工研院 (請參考這則新聞)、澳洲的CSIRO (請參考ArsTechnica的這篇文章)、日本的Semiconductor Energy
Lab (請參考這篇) 等，以後到美國提專利訴訟就都要押擔保金了。
當然這個法案只是草案，連委員會討論都沒過。不過其後續發展，值得注意。此外，我們也可以思考一下它的基本理念，是否就是專利制度針對patent troll問題的解藥呢？大家想想看吧！
以下提供SHIELD 2013原文重點供參。

§ 285A. Recovery of litigation costs
(a) IN GENERAL.—In an action involving the validity or
infringement of a patent—
(1) a party asserting
invalidity or noninfringement may move for judgment that the adverse party does
not meet at least one of the conditions described in subsection (d);
(2) not later than 90 days
after a party has moved for the judgment described in paragraph (1), the

that is filed after the entry of final judgment, any such motion must be
combined with a motion for fees to the prevailing party.
