Are you looking for patent literature specifically about a microneedle patch or array that continuously monitors progesterone and estradiol? I can help with a search strategy and explain what to look for, but I don’t have real-time access to patent databases here. If you want, I can guide you to run a focused search and summarize results you share.
Here’s how to approach it and what to look for:
What to search for
- Core device terms: microneedle, microneedle patch, microneedle array, transdermal microneedle sensor
- Targets: progesterone, estradiol (and synonyms like "estrogen" or "E2")
- Functionality: continuous monitoring, real-time monitoring, real-time sensing, real-time data, continuous telemetry
- Sensing modalities: electrochemical sensor, immunosensor, aptamer-based sensor, optical sensor, wearable biosensor, transdermal sensor
- Biofluid context: interstitial fluid, interstitial tissue, sweat (less common for progesterone/estradiol but sometimes mentioned)
- Additional features: wireless data transmission, integrated electronics, microfluidics, patch/adhesive wearable
Useful search queries (combine with AND/OR)
- (microneedle OR microneedle patch OR microneedle array) AND (hormone OR progesterone OR estradiol) AND (sensor OR monitoring OR detection)
- (microneedle patch) AND (progesterone OR estradiol) AND (electrochemical OR immunosensor OR aptamer)
- (continuous monitoring OR real-time) AND (microneedle) AND (progesterone OR estradiol)
- (interstitial fluid) AND (progesterone OR estradiol) AND (sensor OR transdermal)
- (wearable) AND (microneedle) AND (hormone) AND (sensing)
Patent databases and how to use them
- Google Patents (easy to search, good for keyword hits and families)
- Espacenet (European Patent Office, strong for global families)
- USPTO Patent Full-Text and Image Database (for US filings)
- WIPO PATENTSCOPE (PCT/WO publications, useful for international coverage)
- Pro tip: search by keywords in titles/abstracts, then dive into the claims to see what is actually protected.
What to extract from results
- Publication/Patent family: title, abstract, inventors, assignee, publication date, and CPC/IPC classifications
- Key claim scope: what exactly is claimed (device structure, sensing modality, target hormones, biofluid, continuous/real-time aspect, data transmission)
- Advantage or problem solved: why this approach is novel over prior art
- Any mention of progesterone and/or estradiol specifically (as opposed to general hormone monitoring)
- If possible, look for experimental data or in vivo data showing continuous monitoring
Potential hurdles to expect
- Hormone concentrations for progesterone and estradiol are relatively small and can be challenging to sense in interstitial fluid with high specificity; many microneedle biosensors target other analytes (glucose, cortisol, lactate). Be mindful of cross-reactivity and binding issues.
- Continuous real-time monitoring of steroid hormones via microneedles is a newer area; you may find more patents on transdermal drug delivery or non-continuous hormone sensing rather than long-term continuous monitoring.
- Some filings may cover “hormone sensing in interstitial fluid” broadly and not name progesterone/estradiol explicitly; read the claims to see if you can map them to your targets.
What I can do next (optional)
- If you paste a few patent numbers or links you find, I can summarize their relevance, teach you how strong the claims look, and organize them by priority date, assignee, and coverage.
- If you want, I can draft a sample search plan with a checklist you can reuse across databases, and suggest specific CPC/IPC codes to try (and how to filter for wearable/microneedle sensing).
If you’d like, tell me:
- Do you want US-only results or worldwide (WO/EPO/EP, JP, CN, etc.)?
- Are you okay with me proposing a curated list if you provide a few example hits, or would you prefer a step-by-step plan you can execute yourself now?
I can tailor the guidance to your goals (due diligence, freedom-to-operate, competitive landscape, or inspiration for your own patent claims).
