If you thought there were a lot of patent battles, you haven't seen anything yet.
Clashes between tech titans are likely to become more prevalent since the Obama administration rejected an import ban on older iPhone and iPad models on the AT&T network, said Chris Carani, a partner at the law firm McAndrews Held & Malloy.
It was the first presidential veto of its kind in 25 years.
The ban, ordered by the U.S. International Trade Commission, was to go into effect Monday. It stemmed from a lawsuit between Samsung and Apple regarding a "standard essential patent," which is a patented technology that is used across various devices and meets a technical standard.
For example, 3G technology, which is used in mobile devices such as smartphones and tablets. Because a standard essential patent covers technology that is necessary for companies to compete in a certain field, companies holding those patents are required to license it on "fair, reasonable and nondiscriminatory" rates.

In the case of Samsung and Apple, Samsung said that the iPhone maker was not willing to negotiate a fair rate to license its patented technology, which was a technology related to the interoperability of devices. So, Samsung took its battle to the ITC, seeking a ban on the older Apple devices, which Samsung believed infringed its patent.
