Patent landscape (preliminary)
Prepared 2026-10-03 as a starting point for patent counsel. This is not a legal opinion and not a freedom-to-operate (FTO) clearance. It comes from a web search of Google Patents and USPTO listings. It is US-focused, uses Google Patents' legal-status data (not authoritative), and the full claim text was read only where quoted. China, Europe, Japan, Korea and pending applications were not searched systematically.
Conclusion: Cookwala must not be treated as free of patent concerns. Risk is low for publishing the specification, schemas, vocabularies and recipe data. It is higher for software that executes cooking: the reference hub (orchestration of robots and appliances), appliance control, automatic ordering, and inventory-based matching. Get an FTO opinion before releasing those components.

US8145854B1, claim 1 (verbatim) #
A method for controlling one or more automated food preparation systems, the method comprising the steps of: parsing one or more commands in a recipe by automatically extracting a list of ingredients and one or more measurements for the ingredients required for the recipe; automatically determining one or more pieces of equipment needed to fulfill the one or more commands; automatically generating one or more sequences of instructions for the one or more automated food preparation systems to control the one or more pieces of equipment; automatically transmitting the one or more sequences of instructions to the one or more automated food preparation systems; monitoring the execution of the one or more sequences of instructions on the one or more automated food preparation systems; and automatically creating any additional instructions necessary to ensure proper execution of the one or more sequences of instructions on the one or more automated food preparation systems.
Questions for counsel: does a hub that reads a pre-structured Cookwala document (equipment and quantities already declared) "parse" and "determine equipment"? Does dispatching tasks to executors that translate them into device commands count as "generating sequences of instructions … to control equipment"? Are retries/reassignment "creating additional instructions"? Is there invalidating prior art before June 2006?
2. Helpful prior art (publicly disclosed earlier) #
- WO2014131205A1 (2014): programmable smart cooking machine with XML recipe programs.
- US20030139843A1 (2003): automated cooking driven by machine-readable indicia + cooking programs.
- US8344294B2: cooking according to a C-value (sensor-driven doneness).
- US20140170275A1: system for automating cooking steps.
- HACCP (decades old), the FDA Food Code, schema.org Recipe (2011+), CloudEvents, MQTT, Matter.
- Academic: PDDL/LTL recipe planning, food-state recognition (see RESEARCH.md).
3. Risk by component (non-legal assessment) #
| Component | Risk | Notes |
|---|---|---|
| Specification, schemas, vocabularies, API definitions | Low | Data formats rarely infringe method/apparatus claims on their own |
| Public index (static data, search, filters) | Low–moderate | Search/dietary filtering is a crowded area (#9) |
| Reference hub (orchestration, dispatch, monitoring, retries) | Higher | #1, #2 |
| Appliance bridges (Matter etc.) | Moderate | #2, #10 |
| Auto-ordering, standing rules | Higher | #3 |
| Inventory matching, expiry suggestions | Moderate | #8 |
| Robot executors / motion skills | Device makers' concern | #4, #6, #7 |
4. Recommended actions #
- FTO opinion from a patent attorney before releasing the reference hub, appliance bridges, commerce adapter or inventory matching. Include non-US jurisdictions (CN, EP, JP, KR) and pending applications. Chinese cooking-robot filings are numerous.
- Release in risk order: spec + schemas + vocab + index + recipe data first; hold back execution and commerce components until cleared.
- Design choices that lower risk (confirm with counsel):
- Human approval by default for every order; no purchase without confirmation unless counsel clears standing rules.
- Leave catalog matching and checkout to the merchant (UCP/ACP side).
- Keep device-command generation inside vendors' own executors; the hub dispatches declarative tasks only.
- Never record or replay human motion; keep
skillas an opaque vendor reference.
- Defensive publication: publish the spec with dated releases (git tags, GitHub releases), and consider a defensive publication service (e.g. Technical Disclosure Commons) so later filings can't claim these ideas.
- Network protection: ask counsel about joining LOT Network (protection from patents transferred to non-practicing entities) and whether filing defensive patents makes sense, given the patent pledge.
- Re-check statuses before decisions. Maintenance-fee lapses and expirations change over time.
