在美國最高法院對Alice的判例確定後，許多軟體或商業方法的專利面臨越來越多有關於專利適格性(35 U.S.C. 112)的挑戰。在聯邦法院的專利訴訟中，許多軟體或商業方法的專利都因不具專利適格性而被判專利無效。

      然而，也非所有的專利都被判專利無效，DDR Holdings, LLC v. Hotels.com一案，該系爭專利在聯邦法院中被判定具專利適格性，因此值得進一步探討DDR Holdings, LLC v. Hotels.com中的技術。

      系爭專利為DDR Holdings, LLC所有，主要的claim 19為：

A system useful in an outsource provider serving web pages offering commercial opportunities, the system comprising:

(a) a computer store containing data, for each of a plurality of first web pages, defining a plurality of visually perceptible elements, which visually perceptible elements correspond to the plurality of first web pages;

      (i) wherein each of the first web pages belongs to one of a plurality of web page owners;

      (ii) wherein each of the first web pages displays at least one active link associated with a commerce object associated with a buying opportunity of a selected one of a plurality of merchants; and

      (iii) wherein the selected merchants, the outsource provider, and the owner of the first web page displaying the associated link are each third parties with respect to one another;

(b) a computer server at the outsource provider, which computer server is coupled to the computer store and programmed to:

      (i) receive from the web browser of a computer user a signal indicating activation of one of the links displayed by one of the first web pages;

      (ii) automatically identify as the source page the one of the first web pages on which the link has been activated;

      (iii) in response to identification of the source page, automatically retrieve the stored data corresponding to the source page; and

      (iv) using the data retrieved, automatically generate and transmit to the web browser a second web page that displays: (A) information associated with the commerce object associated with the link that has been activated, and (B) the plurality of visually perceptible elements visually corresponding to the source page.

     系爭專利為一種產生具有視覺元素的網頁與第三方商家的內容相結合的網頁技術，當主機網站的廣告鏈接被點擊時，系統不是將訪問者帶到第三方商家網站，而是生成並引導訪問者到組合網頁，顯示來自第三方商家的商品信息，但保留主機網站的外觀和感覺。因此，聯邦法院的法官認為系爭專利並非屬於抽象概念的軟體專利，因此並未違反美國專利法的規定。 這個判例是Alice案後，少數被認為具專利適格性的專利，專利從業人員應確保他們的專利請求項包含如何操縱計或通信網絡的相互作用以產生比互聯網常規或常規使用更多的期望結果。
