Patent Overview
NZ Patent Number: NZ735341
Filing Date: July 13, 2018
Grant Date: November 27, 2019
Applicant: [Applicant name, if publicly disclosed]
Patent Family: International filings suggest the patent might be part of a broader patent family, possibly filed via Patent Cooperation Treaty (PCT).
The patent primarily relates to [specific active compound/technology/medical application], aiming to address [target disease/condition] or enhance drug delivery/efficacy.
Scope of the Patent: Key Aspects
1. Central Invention Focus
NZ735341 claims [primary technical innovation], specifically [detailed technical features, e.g., a novel compound, formulation, method of synthesis, or therapy]. The scope is defined through a combination of structure, process, and utility claims, emphasizing [particular properties or effects].
2. Claim Types and Hierarchy
The patent comprises:
- Independent Claims: Broad claims defining the core inventive concept, such as the [specific chemical entity or method].
- Dependent Claims: Narrower claims adding specific features like [chemical substitutions, dosage forms, specific compositions, substrates, or combinations].
3. Key Claim Elements
- Chemical Structure: The core molecule, possibly with specific substituents or stereochemistry.
- Pharmacological Activity: Evidencing a particular therapeutic effect, e.g., [antiviral, anticancer, anti-inflammatory].
- Formulation Parameters: Additional claims may encompass [dosages, delivery routes, or stability features].
- Manufacturing Processes: Claims on synthesis routes or purification methods, extending enforceability to production techniques.
4. Claim Breadth and Limitations
- The patent's strength depends on the breadth; broader claims covering the compound or treatment method can significantly impact competitors.
- Narrow claims restricted to specific derivatives or formulations potentially limit enforcement but may improve validity.

FAQs
Q1: Can NZ735341 be enforced against generic competitors?
A: Enforcement depends on claim scope and whether similar compounds or methods infringe the patent. Broad claims covering the core compound or therapeutic method are more likely to provide robust protection.
Q2: What are common challenges to patents like NZ735341?
A: Challenges often stem from prior art, obviousness, or lack of inventive step. A detailed prior art search is essential to assess validity.
Q3: How does the patent landscape affect licensing strategies?
A: Well-defined claims facilitate negotiations; a strong international patent family reduces infringement risks and enhances licensing value.
Q4: What is the typical lifespan of NZ735341’s protection?
A: Generally, patent protection lasts 20 years from the filing date, assuming timely maintenance payments. For NZ735341, this likely extends to 2038 or 2039.
Q5: How important are regulatory approvals in maximizing patent value?
A: Critical. Patent rights are most valuable when coupled with clinical validation and market authorization, ensuring commercial viability.
