Patents involving polymer grafting.

S. No.	Patent publication number	Summary of the invention	References
1.	US 20040208931 A1	Two polymers were used to create the dosage form, with the first polymer serving as the deposit and containing the active ingredient, and the other one, a polyvinyl alcohol-polyethylene glycol graft copolymer, serving as the cover layer (PVA-PEG)	Chen et al. (2005)
2.	US 7419685 B2	In this case, solid dosage forms are created using a water-swellable graft copolymer or a combination of graft copolymers as a polymeric binder.	Mundargi et al. (2007a)
3.	WO 2007115381 A2	It entailed employing PVA-PEG copolymers, such as Kollicoat IR, to make solid dispersions of bioactive chemicals having low water solubility and dissolution rates.	Silva et al. (2009)
4.	US 17/243,133	The synthesis and applications of an ofloxacin-imprinted polymer with an AM-type polystyrene microsphere are covered by this patent. Current technology can considerably improve a drug’s efficacy against Gram-ve and +ve bacteria, with S-antibacterial ofloxacin being 8 to 128 times more effective than its enantiomer R-ofloxacin.	Toti and Aminabhavi (2004)
5.	US 14/548,383	In this invention, a device with an enhanced porosity membrane was described. The modified porous membrane is a porous membrane that has a polymer coating grafted onto it. The device is used to identify analytes using immunoassays in biological samples.	Sutar et al. (2008)
6.	US 16/479,583	In this patent, a reconfigured alginate copolymer with an alginate spine and a grafted substituent attached to one of the alginate backbone’s hydroxyl groups was described.	Mundargi et al. (2007b)
7.	US 6,384,110	This patent described a unique graft copolymer that is created by combining different monomers, such as methyl methacrylate and styrene, with an oil-modified polyurethane resin.	Kulkarni and Sa (2009)
