* Many printer manufacturers claim that if any ink cartridges, beyond those sold by themselves, are used in the printer, the warranty of the printer becomes void. [[Lexmark International, Inc. v. Static Control Components, Inc.|Lexmark tried to go further]], making ink cartridges containing an authentication system, the purpose of which was intended to make it illegal in the United States (under the [[Digital Millennium Copyright Act|DMCA]]) for a competitor to make an ink cartridge compatible with Lexmark printers.<ref>{{cite web |url=http://news.cnet.com/2100-1023-979791.html |title=Lexmark invokes DMCA in toner suit |author-last=McCullagh |author-first=Declan |date=2003-01-08 |website=CNET |access-date=2013-07-07}}</ref> The United States Court of Appeals for the Sixth Circuit held in 2004 that third parties replicating such devices purely to make their cartridges interface with printers does not in fact violate the DMCA.
* Test strips for [[glucose meter]]s are typically made for a specific make or model. Strips designed for [[roche|Accu-chek]] devices, for example, are incompatible with meters from other manufacturers. This lack of standardization can lead to problems especially in [[Developing country|developing countries]], where glucose meters and their associated strips are a scarce commodity. Some companies, despite claiming to have lifetime warranty on their products, stop making specific models and their respective strips so that even those who have a good functioning model have to buy a new model.<ref name="Babaria">{{cite news |url=https://www.nytimes.com/2013/11/15/opinion/a-haitian-boys-needless-death.html?_r=0 |title=A Haitian Boy's Needless Death From Diabetes |author-last1=Babaria |author-first1=Palav |author-last2=O'Riordan |author-first2=Aisling |date=2013-11-14 |work=[[New York Times]] |access-date=2014-07-17 |archive-date=2014-07-26 |archive-url=https://web.archive.org/web/20140726130336/http://www.nytimes.com/2013/11/15/opinion/a-haitian-boys-needless-death.html?_r=0 |url-status=live }}</ref>
* The [[keurig#Keurig K-Cup brewing systems|K-Cup]] single-serving coffee pod system was covered by a patent owned by [[Keurig]], which is a subsidiary of [[Keurig Dr Pepper|Green Mountain Coffee Roasters]], and no other manufacturer could create K-Cup packs compatible with Keurig coffee makers without a license from Keurig. While the company does have patents on improvements to the system, the original K-Cup patents expired in September 2012.<ref name="wsj-kcuppatentdead">{{cite web |title=The K-Cup Patent Is Dead, Long Live The K-Cup |url=https://blogs.wsj.com/corporate-intelligence/2012/11/28/the-k-cup-patent-is-dead-long-live-the-k-cup/ |work=[[Wall Street Journal]] |access-date=2014-03-08 |archive-date=2018-11-23 |archive-url=https://web.archive.org/web/20181123223425/https://blogs.wsj.com/corporate-intelligence/2012/11/28/the-k-cup-patent-is-dead-long-live-the-k-cup/ |url-status=live }}</ref> Other [[:Category:Single-serving coffee|single-serving coffee]] brands, such as [[Nespresso]], also have proprietary systems.
* [[Lens mount]]s of competing [[camera]] manufacturers are almost always incompatible. Therefore, a photographer with a set of lens mounts of a certain manufacturer will prefer not to buy a camera from another manufacturer.
* [[Nvidia]], as of 2018, still only supports the proprietary [[Nvidia G-Sync]] despite the availability of the open [[Video Electronics Standards Association]] (VESA) standard Adaptive Sync technology ([[FreeSync]]). In January 2019, Nvidia announced that it will advance compatibility of its video cards with FreeSync-compatible monitors.<ref>{{cite web |author-last=Kerns |author-first=Michael |title=The (Unproductive) Battle of FreeSync and G-Sync |url=http://www.gamersnexus.net/guides/2373-op-ed-unproductive-battle-of-freesync-and-gsync |website=Gamer's Nexus |access-date=2016-10-11 |archive-date=2016-11-01 |archive-url=https://web.archive.org/web/20161101205856/http://www.gamersnexus.net/guides/2373-op-ed-unproductive-battle-of-freesync-and-gsync |url-status=dead }}</ref>
*Some cordless tool manufacturers make batteries that fit only their own brand of tools, and often are not backwards compatible.  Often multiple brands are owned by the same company, and share tool designs and features, accessories and batteries are deliberately changed to make them incompatible.  An example would be [[Stanley Black & Decker]] which also owns or manufactures [[Black+Decker]], [[DeWalt]], [[Porter-Cable]], Mastercraft, and [[Craftsman (tools)|Craftsman]]. All use almost identical batteries, yet all have some feature designed to stop use in other tools.{{Citation needed|date=May 2022}}
*[[Dell]] laptops will 'throttle', or limit the processing speed available to the end-user, if genuine Dell OEM power supplies are not used with their devices (Users are presented with the warning: "The AC adapter type cannot be determined. This will prevent optimal system performance.").<ref>{{Cite web|title=How to Troubleshoot AC Adapter Issues {{!}} Dell US|url=https://www.dell.com/support/article/en-us/sln128918/how-to-troubleshoot-ac-adapter-issues?lang=en|access-date=2020-07-20|website=www.dell.com|archive-date=2020-07-20|archive-url=https://web.archive.org/web/20200720230951/https://www.dell.com/support/article/en-us/sln128918/how-to-troubleshoot-ac-adapter-issues?lang=en|url-status=live}}</ref>
