Which “heparin patent application” are you looking for?
“Heparin patent application” can refer to different things: a specific patent filing for a new heparin product, a process for making heparin, a new formulation (like an injectable or topical form), or an unrelated filing that includes the word “heparin” in the title/claims. The exact answer depends on which applicant/company, geography (US/EPO/WO), and approximate year you mean.
If you share any of the following, I can narrow it to the right application and summarize it:
the company/applicant name, patent number (if you have one), publication number (WO/US/EP), or filing/publication year.
What to search for in patent databases
Most “heparin patent application” searches come down to filtering by:
1) Title/abstract keywords: heparin, low-molecular-weight heparin, LMWH, anticoagulant, depolymerization, purification, or formulation
2) Claims keywords: “heparin,” “heparin composition,” “process for preparing,” “pharmaceutical composition,” or specific delivery forms
3) Publication type and region: WO (PCT), US, EP, CN, etc.
4) Status: application published, granted, abandoned, or under opposition/litigation
If your goal is to find the most relevant application(s), tell me the country (or “global”) and approximate timeframe.
How “heparin” patents usually fall into categories
Because “heparin” is an established biologically derived anticoagulant, newer patent applications often focus on one of these areas:
- Production/purification or process improvements (to change yield, purity, or consistency)
- Specific heparin fractions or depolymerization methods (including LMWH or other related fractions)
- Formulations (storage stability, delivery method, combination products)
- Manufacturing controls that support regulatory approval and batch-to-batch consistency
If you meant “heparin patent expiry,” what matters
Patent and exclusivity timing depends on:
- The specific patent family (not just the product name “heparin”)
- Jurisdiction (US vs EU vs other)
- Whether there are multiple layers of IP (composition claims, process claims, formulation claims)
- Regulatory exclusivity terms, if applicable

Reply with one detail (any one is enough): the applicant/company name, a patent/publication number, or the approximate year. Then I’ll pull the right “heparin patent application” and summarize what it covers and its current status.
