FAQs
Q1. What is the typical expiry period for Danish pharmaceuticals patents like DK3607962?
A: Generally, pharmaceutical patents filed around 2015—assuming normal patent term calculations—expire approximately 20 years after filing, around 2035. However, patent term extensions or supplementary protection certificates (SPCs) can extend protection up to 5 additional years[1].
Q2. How does DK3607962 protect the inventor’s rights across Europe?
A: If derived from a European patent application, DK3607962 benefits from European patent protection granted under the EPC, enforceable in all member states where validation occurs. Its scope depends on the claims' language and prosecution outcomes.
Q3. Can DK3607962 be circumvented by competitors?
A: Yes, competitors can design around claims by modifying chemical structures, formulations, or therapeutic methods. The scope and specificity of claims dictate how easily they can be bypassed.
Q4. What strategies can patent holders employ to defend their rights against invalidation?
A: They can maintain detailed experimental data to support novelty and inventive step, conduct extensive prior art searches, and file defensive or divisional patents to cover alternative embodiments.
Q5. How does the patent landscape influence clinical development and commercialization?
A: A strong patent portfolio, including DK3607962, provides market exclusivity, incentivizes investment in commercialization, and deters infringement. Conversely, overlapping patents or legal uncertainties may delay development timelines.
