Defensive Portfolio Building Guide

1) Set defensive objectives and a “threat model”

Goal: Decide what “defense” means for your business and who you must deter.

Actions

• Define your top risks: direct competitors, patent-assertion entities, platform incumbents, and key suppliers/customers who demand indemnities.
• Pick 3–10 “must-deter” entities and the product lines/features that matter most.

Why this matters: Defensive portfolios work by creating deterrence and counter-suit leverage—not by merely “having patents.”

Deliverables:

• Threat list (entities + products)
• “Where we cannot be blocked” feature list

2) Run invention harvesting on a cadence (monthly/quarterly)

Goal: Build a pipeline of invention disclosures tied to real products and a future roadmap.

Actions

• Hold structured harvesting sessions with R&D/product (30–60 min):
  
  • New features shipped
  • “Hard-to-replace” architecture decisions
  • Performance, security, and reliability techniques
  • Integration/interop workflows
• Capture: problem, solution, variants, alternatives, implementation details, and product mapping.

Deliverables:

• Standard invention disclosure packets with diagrams + alternatives
• Claimable feature list (core + adjacent variations)

3) Triage inventions for defensive value (not just novelty)

Goal: Prioritize inventions that increase deterrence and negotiation power.

Scoring rubric (example)

• Competitor overlap: likely reads on competitor revenue features?
• Design-around difficulty: can a competitor cheaply avoid it?
• Breadth potential: can you claim across variants?
• Business criticality: does it cover “must-have” capability?

Why: A “well-developed” portfolio emphasizes core business features and functions that transcend a single product version.

Deliverables: Ranked docket: File / Publish defensively / Keep as trade secret / Defer

4) Do a traditional patentability search (per invention)

Goal: Validate novelty/non-obviousness and shape the spec to survive examination.

Actions

• Conduct a prior art search (patents + non-patent literature).
• Identify the closest references and claim-differentiating features.
• Build an IDS plan (U.S.) and a reference map.

Why: Prior art searching helps avoid predictable rejections and supports efficient portfolio buildout.

Deliverables:

• Patentability memo (short-form)
• Feature-to-prior-art matrix

5) Use PioneerIP Patent Infringement Search to find where your products are at risk

Goal: Defensive strategy starts with knowing where competitors can credibly assert against you.

Actions (quarterly + before major launches)

• Input competitors' patents and applications.
• Run infringement-style searches against own products
• Cluster results by product module/feature, and rank by:
  
  • Apparent claim coverage (high/med/low)
  • Assignee threat level
  • Jurisdiction relevance

Why: Defensive patenting aims to avoid being dragged into infringement suits and to reduce exposure through preparedness and portfolio positioning. 

👉WIPO Patent drafting course

Deliverables

• “Exposure heatmap” (feature → risky patents/assignees)
• Target list for counter-coverage filings (next step)

6) Convert risk findings into competitor-focused filing targets

Goal: Build patents that create credible counter-pressure if a dispute happens.

Actions

For each high-risk competitor cluster:

• Identify the competitor feature you believe is hard for them to change
• Identify your internal implementation (and alternatives) that can be claimed to read on their approach

Why: Defensive uses include deterring competitor suits and enabling counter-suit/cross-licensing—this requires a well-developed portfolio.

Deliverables: “Counter-coverage backlog” aligned to competitor risk

7) Amend Pending Claims with Claim Optimizer (build enforceable breadth)

Goal: Produce strong defensive assets by optimizing claim scope and fallback positions.

Actions (drafting workflow)

1. Start with 1–2 independent claims (system/method) mapping to the “locked-in” competitor behavior.
2. Use Claim Optimizer to:

• Detect narrowing limitations that don’t add defensive value
• Suggest broader language where support exists in the spec
• Ensure you have layered fallbacks for prosecution

Why: Defensive portfolios are about creating patents that can function as deterrents and support counter-suit leverage; claim scope discipline is central to that outcome. 

👉WIPO Patent drafting course

Deliverables:

• Claim set with breadth + fallback ladders
• Spec built for prosecution flexibility

8) Prosecution strategy: preserve breadth while earning allowance

Goal: Get granted claims without giving away defensive leverage via avoidable narrowing.

Actions

• Before responding to Office Actions, use Claim Optimizer to evaluate:
  
  • Which amendments shrink defensive coverage
• Prefer strategies that maintain optionality:
  
  • Multiple claim scopes pending
  • Continuations (when justified)
  • Jurisdiction staging (U.S. first, then PCT/foreign as needed)

Why: Claim targeting and breadth can materially affect enforceability and design-around risk. 

Deliverables:

• Response strategy memo: what we concede vs preserve
• Continuation plan for defensive claim families

9) Portfolio maintenance: audit, prune, and refresh

Goal: Keep the defensive portfolio aligned with products and threats.

Actions (semi-annual/annual)

• Audit patents/applications:
  
  • Still mapped to shipped products?
  • Still relevant to the competitor threat model?
  • Still aligned with the roadmap?
• Retire dead weight; reinvest in claim families that create leverage.

Why: Defensive portfolio strategy should be dynamic, including audits and adjustments as threats evolve. 

Deliverables: Portfolio audit report + budget reallocation

10) Continuous competitive monitoring (closed loop)

Goal: Keep detecting new risks and converting them into counter-coverage.

Actions:

• Use PioneerIP Patent Infringement Search on a schedule:
  
  • New competitor products
  • Newly granted competitor patents in critical areas
  • Litigation-driven assignees entering your space
• Feed results back into:
  
  • invention harvesting prompts
  • claim drafting targets
  • continuation strategies

Why: Defensive strategies depend on understanding the competitive landscape and adjusting resource allocation and market position.
