patent strategy general
As soon as possible:
• How likely is competition? Danger of patent filing by competitors or publication
• Observe patent strategy of competitors
As soon as necessary:
• estimate development time (<20yrs?)
• Development projection:satisfy 18m to disclosure?
• Is the market ready?

Advantages:
- Flexibility
- Competitors long in the dark
- Developments of the invention can be used for drafting more precise claims
- Diversion divisional applications
- DE: “Branch off” of utility model from pending application
- …
Disadvantages:-Filed vs. granted patents in patent statistics (portfolio value, stakeholder)-Poorer legal position in case of infringement-Utility patents not for procedures, methods

Differences to technical patents:
- Long development time (10 – 20 yrs.)
- Long product cycle (30 yrs. or more)
- High costs of development (NCE 500- 1000 Mio. €)
- High value of single invention
- High risk
- Special IPR for use („medical use“)
- Registration procedure necessary
- SPCs / term extensions

where
Due to high investment: broad protection necessary
First filing national (to win priority year), PCT focussed to:
• Developed countries (potential production sites)
• Market (with premium price!)
• Countries where patent protection influences sales price (e.g. EU, CN)
Costs for filing + prosecution often of secondary interest
Often > 20 countries
Reason:
• competitors will use regional patent gaps as high profit margins give good opportunities, even if the market is limited to small countries.
• Reduce development/production in "patent-free countries“ –changed situation in China, India (Israel)
• Expensive development + authorization procedure must be recouped through worldwide revenues.

Patenting of new galenic formulation
Pharmaceutical formulation affects:Compatibility (as altered side effect profile with a slower rise in level)Duration (1 * daily instead of 3 * day)Potency (better bioavailability - 300mg instead of 1000 mg)Durability (3 years instead of two years)Administration (tablet instead syringe)
New formulations often have therapeutic benefits and higher patient complianceTo block generics, old formulations are taken off the market, dropping the original marketing authorisation.

Example Degussa / AstaMedicaP1 First mention of the basic structure "AM" as part of a substance class -Markush structure, disclosure preparation, no effect or impact rather unspecific as another list of possible applications, especially interesting compounds only in large list or combination of listsRegistration abroad eg. FR / BE / ZAProtection: 1967-1987 (1984)
P2 patent of addition, divisional application,Diversion from P1 with disclosure ofStructure "AM" explicitly, but as oneof many examples, mentioningpossible uses (FR / BE / ZA) protection as above
