IP Strategy โ deep dive
This page supports the Week 8+9 IP Strategy sprint. Use it if you want to do a prior art search or need more background on patent types.
Chinese vs U.S. patents โ why you will find both
Section titled โChinese vs U.S. patents โ why you will find bothโWhen you search for prior art, AI tools and databases return many U.S. patents. This is normal โ the U.S. database is large, English-language, and well-indexed. A U.S. patent does not protect someone in China; a Chinese patent does not protect you in the U.S.
| China โ CNIPA (ๅฝๅฎถ็ฅ่ฏไบงๆๅฑ) | U.S. โ USPTO | |
|---|---|---|
| Invention patent (ๅๆไธๅฉ) | 2โ3 years ยท registration fee ~ยฅ1,000โ3,000 | 2โ3 years ยท registration fee ~$1,000โ2,000 |
| Utility model (ๅฎ็จๆฐๅ) | 6โ12 months ยท cheaper ยท hardware/functional innovations | No equivalent |
| Useful for your project | Filing in China if you commercialise here | Prior art research only |
Important: The figures above are official registration fees only. Attorney and agent fees are additional โ often several times higher, especially in the U.S. Total cost for a U.S. invention patent with professional help can exceed $15,000.
For most student teams: you will not patent. This section is about deciding which alternative protection fits your product.
If someone on your team already has a patent โ that experience is useful here. Use it.
The AI prior art workflow โ two steps
Section titled โThe AI prior art workflow โ two stepsโUse any AI tool that includes web search โ DeepSeek, Kimi, ChatGPT, or Claude. Web search matters because you need real links to patents and products, not invented ones.
Do not skip Step 1. It sets the AIโs role and prevents generic output.
Step 1 โ paste this as the System Prompt (or first message):
Act as a Technical IP Analyst. Your goal is to help an engineering teamperform a 30-minute Prior Art scan.
Use simple, professional English suitable for an EMI context.
Search for both Chinese (CNIPA) and international (USPTO/WIPO) patentsand products.
Focus on Utility Models for hardware and Trade Secrets for code.
Do not provide generic legal disclaimers. Provide specific, technicalcomparisons.Step 2 โ fill in the blanks and send this as your request:
I am building [one sentence: what it does and who it is for].My core technical approach is [how it works โ e.g. ultrasonic sensorsconnected to a Raspberry Pi].
Tasks:
1. Prior Art: Find 3 existing patents or commercial products that use a similar technical approach. For each: name, one-sentence description, and a link.
2. Technical Gap: Based on those 3, what is one incremental difference my project has? (e.g. cheaper materials, different sensor placement, specific user group)
3. Sprint Comparison: Create a table comparing Chinese Utility Model (ๅฎ็จๆฐๅ) vs. Trade Secret for this specific project. Compare on: Cost, Speed to obtain, and Protection Strength.
4. Strategy: If we have 0 RMB and 4 weeks left, give one reason to open-source this instead of hiding it.Do not paste the AI output directly into your documentation. Write one paragraph in your own words. That is what โstrategic reasoningโ means in the rubric.
What to write in your Technical Documentation (1 page)
Section titled โWhat to write in your Technical Documentation (1 page)โ- Prior art โ 2โ3 similar products or patents, with links or patent numbers
- Your differentiation โ one or two sentences on what your approach does differently
- Patent decision โ yes or no, and why (cost, time, novelty strength)
- Alternative protection โ if not patenting, which strategy and why
This maps directly to the IP Strategy section in the Technical Documentation template.
