Examples: a new machine, a chemical process, a software algorithm, a medical device

Not all innovations need patents. Other forms of IP protection may be more suitable.

• Covers: books, music, paintings, software source code, photographs
• No registration required (but registration strengthens enforcement)
• Protection lasts typically 70+ years after author's death

• Covers: formulas, algorithms, customer lists, manufacturing processes
• Protection lasts as long as secrecy is maintained
• No registration needed – use NDAs and access controls
• ⚠️ Risk: if someone independently discovers it, you can't stop them

• Covers: shape, pattern, or ornamentation of a product
• Does NOT protect how it works – only how it looks
• Typical term: 10–25 years depending on jurisdiction
• In Europe: Registered Community Design (RCD)

Key databases: Google Patents, Espacenet (EPO), USPTO Patent Full-Text, WIPO PATENTSCOPE

• Free tools: Google Patents, Espacenet
• Professional search: Consider hiring a patent search firm (~€500–2,000)
• Search in multiple languages (EN, DE, JP, CN, FR)
• Look beyond patents: scientific papers, conference proceedings, products

Novelty means your invention must NOT be identical to anything publicly disclosed before your filing date.

Many successful patents are improvements on existing technology – the key is the inventive step.

• Compare your invention side-by-side with the closest prior art
• Focus on the differences – can they be enhanced?
• Consider combining multiple improvements into one patent
• Document everything – lab notebooks, dates, prototypes

• Patent a specific use case not covered by prior art
• Patent an improved method or process
• Patent a novel combination of known elements
• ⚠️ Must still satisfy inventive step (non-obviousness)

• Open Source: Publish and build a community around your invention
• First-to-Market: Launch quickly and rely on speed and brand
• Trade Secret: Keep it confidential if it can't be reverse-engineered
• Academic Publication: Publish a paper for reputation and citations

This is the most commonly contested criterion in patent examinations. Even if novel, an invention can be rejected as "obvious."

A patent attorney can assess whether the combination of features creates a surprising technical effect – which can satisfy the inventive step.

Patents cost money (€3,000–50,000+ over their lifetime). Without commercial potential, the investment may not be justified.

• Academic publication: Build reputation and citations
• Open innovation: Share and collaborate with others
• Utility model: Cheaper, faster alternative (available in some countries)
• Re-evaluate: Is there a different application with market potential?

Patent Attorney: Technical expert who drafts and files applications. Patent Lawyer: Legal expert for enforcement and litigation. Many combine both roles.

• Assesses novelty, inventive step, and industrial applicability
• Reviews your prior art search results
• Recommends strategy: patent, utility model, or alternative
• Can identify claim strategies to maximize protection

• Technical background in your field (engineering, chemistry, CS, etc.)
• Licensed in your target jurisdiction (EPO, USPTO, etc.)
• Experience with similar inventions
• References from past clients
• Fee structure – transparent and predictable

• Freedom-to-Operate (FTO) analyses
• Patent litigation and infringement cases
• Licensing negotiations
• Invalidation proceedings against competitor patents

• ✅ Saves attorney fees (€2,000–10,000+)
• ❌ Poorly drafted claims = weak or invalid patent
• ❌ Missing deadlines can kill your application
• ❌ No professional assessment of patentability
• 💡 Tip: At least use a provisional application to buy time

Invention: Up to 20 years, full examination. Utility Model: ~10 years, faster/cheaper, limited examination. Design: Appearance only, 10–25 years.

• Term: Up to 20 years from filing date
• Examination: Full substantive examination (novelty, inventive step, industrial applicability)
• Cost: €5,000–30,000+ (filing + examination + maintenance)
• Timeline: 2–5 years until grant
• Strength: Highest level of protection

• Term: Up to 10 years
• Examination: Formal only (no substantive novelty check)
• Cost: €1,000–5,000
• Timeline: 3–12 months until grant
• Available in: Germany, China, Japan, Korea, Brazil, Mexico (NOT in US or UK)
• ⚠️ Easier to invalidate in court

Patents are territorial. A German patent only protects in Germany. Choose your strategy based on where your market and competitors are.

• Germany (DPMA): ~€400–500 official fees (filing + search + examination)
• US (USPTO): ~$400–800 (micro to small entity)
• UK (UKIPO): ~£300–400 (filing + search + examination)
• Fastest and cheapest for single-country protection
• ⚠️ You can still file in other countries later (within 12 months via priority)

• File at: European Patent Office (Munich)
• Cost: €5,000–20,000+ (depending on validation countries)
• Validation: After grant, validate in each target country
• Unitary Patent: New system – one patent for 18 EU countries
• Timeline: 3–5 years until grant

• Coverage: 157 countries worldwide
• Cost: €3,000–8,000 (international phase, depending on translation effort and, where applicable, attorney fees)
• Buy time: Delays national phase entry to 30–31 months
• International search report: Early indication of patentability
• Total cost: Can exceed €50,000–100,000 with national phases

Provisional: Lower cost, establishes priority date, 12 months to file full application. Direct: Starts examination immediately, no separate deadline.

• Cost: €500–2,000 (much lower than full application)
• Priority date: Established from this filing
• 12 months to develop, test, and file the full application
• Benefits: "Patent Pending" status, time to find investors, test market
• ⚠️ Risk: Must file full application within 12 months or lose priority

• Includes: Description, claims, abstract, drawings
• Examination starts: Usually within 1–3 years
• Cost: Higher upfront (€3,000–15,000+)
• Advantage: No separate deadline to worry about
• Best for: Well-developed inventions ready for examination

• Title: Clear and descriptive
• Abstract: Brief summary (150 words max)
• Description: Full technical disclosure (enable a skilled person to reproduce)
• Claims: The legal boundaries of your protection (most critical part!)
• Drawings: Figures illustrating the invention

• Formal examination: Are all documents in order?
• Substantive examination: Novelty, inventive step, industrial applicability
• Search report: Examiner finds relevant prior art
• Timeline: 1–4 years depending on jurisdiction
• ⚠️: You may need to request examination (not automatic in all offices)

Most applications receive at least one office action with objections. This is normal – about 60–80% of patents require amendments before grant.

• Narrow claims: Add limiting features to distinguish from prior art
• Argue: Provide arguments why the invention is non-obvious
• Split: File a divisional application for additional inventions
• Multiple rounds: May require 2–4 rounds of examination
• Cost: Each round adds €500–3,000 in attorney fees

Rejection is not the end. Many eventually granted patents were initially rejected. The appeal process or a new filing strategy can still succeed.

• EPO: Appeal to the Boards of Appeal (€2,000+ fee)
• USPTO: Appeal to the Patent Trial and Appeal Board (PTAB)
• Timeline: 1–3 additional years
• Cost: €5,000–20,000+ for appeal proceedings
• Success rate: ~30–50% depending on jurisdiction and grounds

• Use insights from the rejection to improve your claims
• Focus on a different aspect of the invention
• Consider a utility model if invention patent was rejected
• File in a different jurisdiction with more favorable examination practice

A granted patent gives you the right to exclude others from making, using, selling, or importing your invention for up to 20 years.
