MorphoSys AG / MorphoSys Receives First Patent on Novel Antibody Platform Ylanthia in the US .

MorphoSys AG (FSE: MOR; Prime Standard Segment, TecDAX) today announced that the US Patent and
Trademark Office (USPTO) has granted the first patent covering the Company's latest antibody
platform Ylanthia, which became commercially available for existing and new partners in 2012.

"A growing patent portfolio on our new antibody platform Ylanthia is an important factor for a
successful partnering process in our core licensing markets, which we intend to intensify during
the course of 2013", commented Dr. Marlies Sproll, Chief Scientific Officer of MorphoSys AG.

The new patent (US 8,367,586) covers the composition of MorphoSys's Ylanthia antibody library.
Ylanthia comprises more than 100 billion distinct, fully human antibodies, which makes it the
industry's largest known antibody Fab library. It uses 36 fixed, naturally-occurring heavy and
light chain framework combinations, which translates into unprecedented structural diversity. The
library's diversity is expected to result in antibodies against previously inaccessible target
molecules and unique epitope coverage.

Ylanthia's antibody frameworks were pre-selected for expression levels, stability and aggregation
behavior. A shift towards higher stability and stress tolerance will increase shelf life and serum
stability of resulting antibody products, making them more cost-effective to produce and
administer. A higher solubility in turn opens up the path for more convenient ways of
administration, to the benefit of patients. When needed, antibodies from the Ylanthia library are
optimized using MorphoSys's proprietary Slonomics technology. Slonomics enables optimization of
Ylanthia antibodies with unprecedented speed and flexibility.
