tech-route-comparison
Overview
Evidence-backed comparison of two or more technical routes, architectures, or solution paths. Use when the user asks for technical pre-research, technical route comparison, route selection, TRL assessment, maturity assessment, readiness evaluation, opportunity mapping, or any management-grade technical report deliverable — even if they only ask for initiation analysis, committee-ready materials, feasibility, or "which route is better".

Tech Route Comparison
Provided by Patsnap Eureka.
Use this skill when the decision object is a route set rather than a company, a market arena, or a concrete proposal package. The goal is to compare routes on evidence, normalize the comparison basis, and end with a recommendation the user can act on.
Use When
The user asks which technical route is better, more mature, or lower risk
Route comparison across two or more technical approaches
Maturity, readiness, feasibility, or TRL evaluation
Scenario-specific route recommendation (e.g., "which route for EV use?")
Opportunity map or white-space scan across routes
Management-ready technical pre-research report
Do Not Use
The real question is one company in one topic → route to
company-tech-profileThe real question is a multi-player arena or player map → route to
competitive-landscapeThe real question is a concrete proposal or initiation package → route to
rd-initiation-reviewThe task is pure market sizing or commercial comparison with no technical core
Legal patent opinion, FTO, or infringement analysis
Modes
| Mode | When To Use | Focus |
|---|---|---|
overview | Broad technical landscape for a topic | Route inventory, frontier scan, ecosystem structure |
compare | Direct comparison of named routes | Head-to-head comparison matrix, ranking, recommendation |
maturity | Readiness or TRL assessment | Maturity rubric, stage gates, deployment evidence |
opportunity | White-space or opportunity scan | Gap analysis, emerging routes, entry paths |
Default mode: compare when routes are named, overview when only a topic is given.
Core Principles
Scope Freeze Before Retrieval
Freeze these parameters before wide retrieval to prevent evidence drift:
topic: the technology domaindecision_question: what the user needs to decidedecision_use: directional route scan / go-no-go / diligence-gradeapplication_scenario: the specific use case or context (e.g., EV battery, data center cooling, edge inference)comparison_level: material-level / component-level / system-levelknown_routes: user-provided or discovered route settime_window: default last 3-5 years
Comparison Basis Must Be Explicit
Before ranking routes, write down:
What routes are being compared (frozen definitions)
What dimensions are used for comparison (performance, cost, maturity, risk, scalability, etc.)
What normalization rules apply (same application scenario, same comparison level, same time window)
Do not compare shifting route buckets. Do not mix material-level evidence with system-level evidence as if they were the same layer.
TRL And Maturity Require Explicit Rubric
Do not write TRL labels, readiness levels, or maturity claims without an explicit rubric that defines what each level means in the current context. A route with many weak signals is still weak — do not confuse volume with confidence.
Counterevidence Is Required
For every route recommendation, actively search for and document:
Evidence that contradicts the recommendation
Conditions under which the recommendation would change
Update triggers that should prompt re-evaluation
Tool Routing And Fallback
This skill works across multiple tool environments. Before retrieval, detect which capabilities are available and select the highest tier that is reachable.
Tier 1 (Recommended): Structured Patent/Paper Retrieval
Use the host's best structured patent and paper retrieval stack.
This usually means fielded patent/paper search plus record-level deep fetch.
Evidence grade: S/A
Required capabilities: per-route search, keyword or semantic route discovery, and deep-read of shortlisted records.
Tier 2 (Fallback): Web Research + Scholarly Companion Lane
Use the host's best broad web research tool plus a scholarly companion lane when available.
Exa, Tavily, Brave, and domain-specific scholarly databases are good examples, not hard requirements.
Evidence grade: A/B
Coverage loss vs Tier 1: route breadth and patent-structure claims are less precise.
Tier 3 (Fallback): Generic Web Search And Page Reading
Use generic web search and page/PDF reading tools available in the host.
Evidence grade: B/C
Tier 4 (Minimum): User Materials + Reasoned Synthesis
No external tools required
Evidence grade: C/U
Routing Rules
Detect available capabilities at the start of the workflow.
Select the highest available tier as the primary retrieval channel.
When a tier is unavailable, explicitly state the downgrade.
If the tool stack is degraded, lower confidence on route breadth and frontier claims.
Minimum Working Files
Create or update these files in a writable run folder:
request.mdworkplan.mdmethod_decisions.mdcomparison_basis.mdquery_log.csvsource_index.csvclaim_ledger.csvreport.md
Recommended subfolders are described in references/workflow.md .
Default Workflow
Step 0: Freeze Scope
Confirm or infer the following before any retrieval:
topic,decision_question,decision_usemode(overview / compare / maturity / opportunity)application_scenario,comparison_levelknown_routes(user-provided or to be discovered)time_window,audience,deliverable
If the user did not specify routes, proceed with route discovery in Step 1. If the user named routes, freeze them and proceed to Step 2.
If the topic is broad and not route-frozen yet, write a provisional route
taxonomy into comparison_basis.md before retrieval starts.
Step 1: Build Route Taxonomy (When Routes Not Given)
Run 2-3 broad topic searches to discover candidate routes.
Tier 1: structured patent/paper search around the topic
Tier 2: targeted web research plus scholarly companion search
Tier 3/4: generic web or user-provided materials
Extract candidate routes from patent IPC clusters, paper themes, and review articles.
Freeze the route set in
comparison_basis.mdbefore proceeding.If the route set is still too fuzzy, stop and narrow it with the user instead of writing a superficial ranking.
Step 2: Freeze Comparison Basis
Write to comparison_basis.md:
Route definitions (what each route means, technically)
Comparison dimensions (performance, cost, maturity, risk, scalability, deployment readiness, etc.)
Normalization rules:
Same application scenario for all routes
Same comparison level (do not mix material-level with system-level)
Same time window
Scoring approach (if maturity or TRL mode):
Explicit rubric with level definitions
Evidence requirements per level
Step 3: Retrieve Evidence Per Route
For each route independently:
Run 2-3 searches focused on the route's technical specifics.
Tier 1: structured patent/paper search for the route
Tier 2: targeted web research plus scholarly companion search
Tier 3/4: generic web or user-provided materials
Collect evidence across dimensions:
Patent activity and key technical approaches
Paper frontier and recent breakthroughs
Standards, specifications, and regulatory status
Product deployments, benchmarks, and commercial signals
Deep-read 2-3 representative patents/papers per route for technical detail.
Record all searches in
query_log.csvwith per-route tagging.
Do not mix evidence across routes during collection. Keep per-route evidence buckets separate until the normalization step.
Step 4: Normalize And Compare
Build the comparison matrix: routes (rows) × dimensions (columns). Fill each cell with evidence-backed assessments.
Example format:
| Dimension | Route A | Route B | Route C |
|---|---|---|---|
| Performance | High — [Patent: X] demonstrates Y | Moderate — lab-scale only | High — [Paper: Z] benchmark |
| Cost | High — mature supply chain | Unknown — no production data | Low — expensive precursors |
| Maturity (TRL) | TRL 7 — pilot production | TRL 4 — lab validation | TRL 5 — prototype |
| Risk | Low — well-understood failure modes | High — scaling unknowns | Moderate — IP concentration |
Apply the scoring rubric (if maturity or TRL mode):
Score each route per dimension using the explicit rubric
Show the rubric alongside the scores
Do not assign TRL or maturity labels without evidence
Run the counterevidence pass:
For each route recommendation, search for contradicting evidence
Document weakening conditions and update triggers
If counterevidence is strong, adjust the recommendation
Separate every claim into:
Verified fact : directly supported by patent, paper, or official source
Evidence-backed inference : reasonable conclusion from multiple signals
Open gap : insufficient evidence, state what is missing
Step 5: Synthesize And Draft
Write the report following the mode-appropriate output skeleton.

Key evidence references
Opportunity Mode
Executive summary: where the opportunities are
Route landscape and current coverage

Emerging routes and early signals
Recommended investigation priorities
Key evidence references
Every claim must cite its source type and identifier, e.g., [Patent: CN1234567B],
[Paper: DOI or title], [Web: source name].
Completion Gates
All must pass before delivering the final answer:
Route set is frozen before wide retrieval
Comparison basis is explicit and written to
comparison_basis.mdComparison level is consistent (not mixing material/component/system)
At least 2 searches per route executed with results analyzed
Per-route evidence collected independently before cross-route comparison
Comparison matrix present with evidence backing per cell
If TRL or maturity labels are used, explicit rubric is present
Counterevidence pass completed for the main recommendation
Every major claim has a traceable source citation
Verified fact / evidence-backed inference / open gap clearly separated
Tool tier and coverage limitations explicitly stated
If evidence is insufficient for confident ranking, stated explicitly with next-evidence-gathering directions
Guardrails
Do not confuse volume with confidence. A route with many weak signals is still weak.
Do not let vendor or company marketing outrank patents, papers, standards, or directly inspectable technical evidence.
Do not turn raw patent or paper counts into maturity claims without dedup and scope caveats.
Do not write TRL, readiness, or maturity labels without an explicit rubric.
Do not compare material-level, component-level, and system-level evidence as if they were the same layer.
Do not force a strong conclusion when the user only gave a broad topic and the evidence base is thin.
Do not skip the counterevidence pass — every recommendation needs at least one documented weakening condition.
If paper or patent coverage is inadequate for a route, say so explicitly before making strength claims.
Do not present a route ranking as definitive when the comparison basis is incomplete or the scoring rubric is missing.
Keep the recommendation tied to the stated scenario — a route that is best for one application may not be best for another.
