2012年5月25日，一家名為Canatelo, LLC之公司，向美國波多黎各聯邦地院提告，控告友訊(D-Link Systems Inc.)所生產販售之無線網路攝影機產品及其通路商OfficeMax, Inc.公司，侵犯其所擁有、與視訊監控相關之美國專利。
本案兩項系爭專利分別為美國專利編號US 7,310,111以及US 6,476,858，名稱均為「視訊監控與保全系統（Video monitoring and security system）」，發明人均為Luis G.Ramirez Diaz、Pedro L.Cruz Burgos與Dan F.Rodriquez三人(專利資料顯示均為波多黎各人)，原始權利人則為波多黎各之Innovation Institute，前者於2007年12月核發，後者則於2002年11月核發。
Canatelo, LLC為設立於波多黎各當地的公司，其並無太多公開資訊可供搜尋，同時其與原始權利人Innovation Institute間具備何種關係也不得而知。波多黎各為美國在加勒比海之「未併入領土」(unincorporated territory)，而波多黎各聯邦地院之法律定位與美國其他各州之聯邦地院相同。
根據資料顯示，本案為2011年6月以來第三起在波多黎各聯邦地院提告的專利侵權訴訟；而在另一起專利侵權訴訟案件(Ingeniador, LLC v. Interwoven, Inc. et al.，案號為3:11-cv-01840)，雖然原告亦為設立於波多黎各之公司，但法院認為該案中部分被告與波多黎各的關聯性過小，是故認為對這些被告之專利侵權控告不具備管轄權。這樣的見解是否適用於友訊，或值得進一步觀察。(541字；表2)
表一、請求項解析
| US 7,310,111請求項1 |
US 6,476,858請求項1 |
1. A computer especially suitable for use as a video-based security system comprising:
一項可當成視訊保全系統使用之電腦，其包括 |
1. A video monitoring system, comprising:
一項視訊監控系統，包括 |
a plurality of video inputs (Fig.7 – 1a, 1b, 1c & 1d) each configured to receive an electronic video signal from a video camera;
可從視訊攝影機接收電子視訊訊號之複數視訊輸入 |
a plurality of video cameras, each outputting a video image; a personal computer interfaced to each camera, a display device, video digitization circuitry and an event trigger,
複數個輸出視訊影像之視訊攝影機；與每個攝影機互動之個人電腦，顯示裝置，視訊數位化電路與事件啟動器 |
at least one processor operationally coupled with the plurality of video inputs and configurable to operate on a digital representationof the electronic video signals from the plurality of video inputs;
至少一個處理器，其可以處理複數視訊輸入，並操作來自複數視訊輸入之電子視訊訊號的數位表徵 |
the computer being operative to perform the following functions: a) receive and digitize the video images from each video cameras, b) display the video images in separate windows on the display device, and c) perform a predetermined function in response to the event trigger,
前述電腦可執行下述功能：a) 從每個視訊攝影機接收視訊影像並將之數位化，b)在顯示裝置上以分割視窗顯示視訊影像，c)回應事件啟動器執行預設功能 |
and a network (Fig.7 – 10) connection to the Internet (Fig.7 - 6) operationally coupled with the at least one processor,
接續網際網路之網路，其可與前述處理器連接運作 |
wherein the event trigger is generated by: applying a map having a plurality of masking cells to a new video image (Fig. 9C - 707) and to an old video image (Fig. 9C - 706) so that the new video image and the old video image each include a plurality of unmasked cells completely surrounding the masked cells,wherein the map has the same dimensions as the new video image and the old video image,
事件啟動器是如下產生：就新影像訊號與舊影像訊號產製含有複數個經遮罩之區塊的圖譜，讓新舊視訊影像在其圖譜中均有數個未經遮罩之區塊包圍著經遮罩的區塊，同時該圖譜具備與新舊視訊影像同樣的象限數 |
wherein when the computer detects motion in the electronic video signals, the computer generates a compressed representation that includes the motion,
當電腦偵測到電子視訊訊號有動作時，電腦會產製一個經壓縮的數位表徵，其中包括該動作 |
and wherein the masked cells inactivate a fixed area within the new video image and the old video image, comparing the plurality of unmasked cells of the new video image with the plurality of unmasked cells of the old video image to detect any changed cells in the new video image,
在新舊視訊影像之固定區域中，比較兩者之未經遮罩的區塊數，以偵測在新視訊影像中是否有改變之區塊 |
and wherein the computer automatically transmits the compressed representation through the network connection as part of an e-mail message (Fig.7 – 8) only after detecting the motion,
電腦會在偵測到動作後自動透過網路、以電子郵件訊息一部分之形式傳送該表徵 |
and wherein the computer transmits a separate alarm message approximately simultaneous to the transmission of the e-mail.
電腦在傳送前述電子郵件時，會幾乎同時傳送另一封獨立之通知訊息 |
and applying a filter (Fig. 9C - 711) to the changed cells that eliminates any changed cells in the new video image that are not surrounded by other changed cells in the new video image, and wherein the event trigger is generated when at least one changed cell remains after applying the filter.
並就改變之區塊使用濾波器來消除任何在新視訊影像中未被其該改變區塊所包圍的改變區塊，而事件啟動器之產製便發生於在使用濾波器後仍有未被清除之改變區塊存在 |
