Abstract
PURPOSE: Female urination in the supine position is a frequent bedside need, yet common workarounds (bedpans, diapers, improvised receptacles) can be uncomfortable, increase caregiver workload, and contribute to potentially avoidable urinary catheterization. We mapped the patent landscape of non-invasive female urine-collection technologies intended for supine use and derived actionable innovation and access priorities. METHODS: We searched Espacenet (EPO), WIPO PATENTSCOPE, the USPTO database, Google Patents, and INVENES for January 2000-September 2025. Records were screened for functional relevance to female supine voiding and de-duplicated at the DOCDB family level. For each patent family we extracted priority/publication timing, jurisdictions, assignees, IPC/CPC codes, and forward citations; coded solution archetypes; and coded adoption-relevant attributes (workflow feasibility, infrastructure dependence, and single-use vs reusable design intent). A structured multi-domain appraisal (0-2 per domain; total 0-12) was applied to representative families to support consistent comparison. RESULTS: Twenty-six patent families met inclusion criteria. Innovation activity was sustained but low-intensity and uneven over time, with most filings clustered in 2010-2020; interpretation of late years was limited by publication lag. Most inventions followed single-use/disposable pathways (≈69%). The set covered 16 IPC subclasses, although >60% of families were concentrated in A61F 5/455. Passive external collectors showed the strongest maturity signals. Adhesive patch-type and intravaginal concepts were sporadic and heterogeneous. Suction/capillary approaches introduced stronger containment mechanisms but increased dependence on external infrastructure and proprietary consumables, limiting feasibility in home care and low-resource settings. CONCLUSION: The most consistent gap lies at the intersection of ergonomics, autonomy, and reusability-female-specific supine interfaces that contain leakage without adhesives or invasive elements, operate passively or with minimal infrastructure, and enable sterilizable/reusable pathways. Priorities for R&D include usability- and risk-informed evaluation, sustainability-by-design, and access-oriented IP strategies to support diffusion beyond high-resource settings.
