Source: MaxVal’s Assignment Database . Shire has the exclusive license to the above patents as stated in
the complaint. 

These patents in general covers the FDA approved guanfacine hydrochloride extended release tablets, Eq. 1 mg Base, Eq. 2 mg Base, Eq. 3 mg Base and Eq. 4 mg Base, which is marketed by Shire under the name of Intuniv® and currently[ii] holds the NDA no. 022037 (source: Patent Marker). The suit was filed by Shire et al. against Sandoz for seeking FDA approval to market a generic version of Intuniv (Sandoz Product) (ANDA no. 202568). 

The case now turns out to be closed as the parties entered a Settlement Agreement under which Shire granted
Sandoz the license to ‘Shire Patents’. Sandoz admitted that all the claims in the Shire Patents are valid and enforceable and the sale of Sandoz Product would constitute infringement of the Shire Patents in the absence of license. As the parties have agreed to terminate the pending litigation it is ordered that case is dismissed.
