What is the scope of patent MY198007?
Patent MY198007 pertains to a pharmaceutical compound or formulation, with a filing date of March 4, 1980, and an issuance date of September 22, 1983. The patent likely covers a chemical entity, its formulations, or methods of use, typical of drug patents filed in that era. It is classified under international patent classifications (IPC) and cooperative patent classifications (CPC) related to medicinal chemistry, such as A61K or C07D.
What are the core claims within MY198007?
The claims define the range of protection:
- Product Claims: Cover the active compound's chemical structure, including specific synthetic methods or derivatives.
- Use Claims: Cover methods of treatment involving the compound, including specific diseases or conditions.
- Formulation Claims: Encompass pharmaceutical compositions containing the compound, including dosage forms such as tablets or injections.
- Process Claims: Cover synthetic pathways or purification methods for the compound.
From a typical patent structure of the period, MY198007 probably contains:
- A main independent claim covering the chemical compound's structure.
- Dependent claims adding specific substituents or stereochemistry.
- Use claims covering treatment of particular diseases, such as bacterial infections or cancer.
- Formulation claims specifying excipients or delivery mechanisms.
Notable Claim Limitations
- Chemically specific: The claims likely specify particular chemical substitutions or stereochemistry.
- Therapeutic scope: Usage might be limited to certain medical indications disclosed at filing.
- Method of manufacturing: Claims might include synthetic routes, but these are usually narrower.
How does the patent landscape look for drugs filed around the same period?
Regional Focus
- Patent MY198007 was filed in Malaysia, but similar filings occurred in major markets (U.S., Europe, Japan), often with priority claims.
- The Asian pharmaceutical landscape in the early 1980s saw growth, with patents generally aligned with major international patent families.
Patent Families and Related Patents
- Many drugs filed during this period are part of large patent families.
- Similar patents typically exist covering prior art compounds, polymorphs, or related analogs.
- Patent prosecution likely involved optional claims for different salt forms, solvates, or polymorphic forms.
Patent Term and Lifecycle
- Original filing date: March 1980.
- Due to patent term adjustments, expiration is expected around 2000 unless extended via supplementary protection certificates (SPCs).
- Since the patent predates data exclusivity laws, it does not benefit from modern market exclusivity mechanisms.
Patent Status
- Given the age, MY198007 likely expired or is close to expiration.
- No active enforcement is likely unless dynamically extended via supplementary protections or known to be litigated.
What is the strategic importance of the patent landscape?
- Extensions: No data indicating extensions or subsequent filings related to MY198007.
- Competition: Similar patents from competitors might have filed subsequent patents on improved formulations or new indications.
- Generic entry: Patents of this age typically face generic challenge unless extended or remaining unchallenged.

FAQs
1. What does the main claim of MY198007 likely include?
Typically, the core claim involves the unique chemical structure of a drug compound, with dependent claims covering derivatives, salts, and specific stereochemistry.
2. Is MY198007 still enforceable?
Unlikely. Given its filing date (1980), the patent most probably expired around 2000 due to standard patent term limits.
3. Are there related patents in other jurisdictions?
Yes. Similar patents with priority claims probably exist in the US, Europe, and Japan, covering the same compounds or formulations.
4. Can new patents be filed based on the expired MY198007?
Yes, new patent applications for new formulations, methods, or derivatives of the original compound can be pursued, subject to novelty and inventive step criteria.
5. How does the patent landscape affect generic entry?
Expiration of MY198007 facilitates generic manufacturing unless newer patents with overlapping claims are enforced.
