Beyond speculation to scientific evidence: Unlocking a new paradigm in patent infringement analysis with AI.

Semiconductor patent litigation must be fought with evidence, not intuition. Reverse engineering (RE) a complex semiconductor chip is a costly and time-consuming process. But what if you could revolutionize it using Large Language Models (LLMs)? This guide presents a step-by-step analysis methodology and LLM prompt strategies that in-house patent teams can use to build a robust evidentiary framework for the courtroom.

 

Introduction: The Strategic Importance of Reverse Engineering in Patent Litigation

Patent litigation is a legally demanding process that consumes significant time and resources. Before filing a lawsuit, a plaintiff is obligated to present a ‘reasonable basis’ for believing their patent is being infringed upon by a defendant's product. At this stage, reverse engineering becomes the most powerful tool for demonstrating a concrete possibility of infringement based on scientific analysis, rather than mere speculation. This is especially true before the discovery phase, where direct evidence from the defendant's confidential materials is not yet available; one must often rely solely on RE.

The initial findings from RE are crucial for establishing the validity of a lawsuit, formulating a litigation strategy, and even encouraging an early settlement. A lawsuit initiated without solid RE faces a high risk of dismissal due to insufficient evidence, which can lead to substantial financial losses.

Overview of the Complete Reverse Engineering Workflow

Semiconductor reverse engineering is not random disassembly; it is a highly controlled and systematic forensic investigation. The process generally follows a ‘funnel’ workflow, where the precision, cost, and level of destructiveness gradually increase. Each step is organically linked, using information from the previous stage to define the objectives and methods for the next.

  • Non-destructive Analysis: The initial reconnaissance phase to understand the internal structure of the chip in its packaged state without causing damage.
  • Sample Preparation: The process of exposing the target die and precisely sectioning a specific area for analysis.
  • Structural & Compositional Analysis: The core phase of observing micro-structures with microscopes and analyzing the materials of each component.
  • Specialized Analysis: Analyzing properties not visible with standard microscopy, such as doping concentrations or crystal structures.

The ultimate goal of this entire process is to complete a Claim Chart, a document that provides a clear, one-to-one comparison between the patent claims and the analytical results. The claim chart is the final deliverable that translates all scientific evidence gathered during RE into a legal argument.

Step 1: Strategic Analysis Planning and LLM Utilization

Before beginning the analysis, it is essential to review legal risks and design the most efficient analysis roadmap tailored to the patent claims. An LLM can serve as an excellent strategist in this process.

๐Ÿค– LLM Prompt Example: Legal Risk Assessment


# Role: Intellectual Property Legal Expert
# Task: Assess legal risks of semiconductor RE analysis

Please assess the legal risks for the following analysis plan and propose necessary preliminary measures:
- Target of Analysis: [Competitor's Semiconductor Product Name]
- Proposed Analysis Methods: Decapsulation, FIB-SEM, TEM, SIMS
- Jurisdiction: South Korea, USA, Japan

# Output Format:
{
  "legal_risks": ["List of risk factors"],
  "required_actions": ["Mandatory preliminary steps"],
  "documentation": ["List of necessary documents"],
  "approval_timeline": "Estimated approval timeframe"
}
        

๐Ÿค– LLM Prompt Example: Creating an Analysis Roadmap


# Role: Semiconductor Analysis Strategist
# Task: Create an efficient RE analysis roadmap

# Patent Claim:
[Insert the full text of the patent claim to be analyzed here]

# Competitor Product Information:
- Product Name: [Product Name]
- Publicly Available Technical Specs: [Specifications]
- Estimated Manufacturing Process: [Process Node]

# Requirements:
1. Set analysis priorities for each limitation of the claim.
2. Propose a cost-effective analysis sequence (from non-destructive to destructive).
3. Evaluate the probability of securing evidence at each stage.
4. Develop a risk-mitigation plan for the analysis.

# Output: A detailed analysis roadmap in JSON format.
        

Step 2: Non-Destructive Analysis - Chip Reconnaissance

This initial stage is crucial for understanding the overall architecture of the device, identifying potential manufacturing defects, and strategically planning the subsequent destructive analysis phases. The information gathered here forms the basis for managing risks and maximizing efficiency throughout the entire project.

2.1 SAM (Scanning Acoustic Microscopy) Analysis

  • Purpose: To verify the physical integrity of the product and detect internal defects (e.g., gaps between the chip and its package) to ensure the reliability of subsequent analyses.
  • Principle: Uses ultrasound waves that are directed at a sample. The acoustic waves reflected from internal interfaces or defects are detected to create an image of the internal structure. The C-Scan mode, which provides a planar image at a specific depth, is commonly used.
  • Results Interpretation: Dark or irregular patterns in the image indicate internal defects like voids or delamination. This information serves as a critical warning for areas to be cautious of during subsequent processes like decapsulation.

๐Ÿค– LLM Prompt Example: SAM Image Analysis


# Role: SAM Image Analysis Expert
# Input: [Upload SAM C-Scan Image]

# Task:
1. Classify the defect patterns visible in the image and mark their locations.
2. Determine whether each defect is likely a manufacturing issue or damage from the analysis process.
3. Suggest areas to avoid during the subsequent FIB analysis.
4. Evaluate the impact of the defect density on product quality.

# Output Format:
{
  "defect_classification": {...},
  "analysis_safe_zones": [],
  "quality_assessment": "..."
}
        

2.2 3D X-ray CT (Computed Tomography) Analysis

  • Purpose: To understand the 3D architecture of the chip package (e.g., die stacking, TSV arrays) and to set precise coordinates for subsequent high-precision analysis.
  • Principle: A 3D volumetric dataset is generated by computationally reconstructing numerous 2D X-ray transmission images taken from multiple angles as the sample is rotated 360 degrees.
  • Results Interpretation: The reconstructed 3D model allows for a direct comparison between the patent drawings and the actual product's structure. For instance, if a patent claims an 'eight-layer stacked memory die,' the CT image can verify if eight dies are indeed stacked. This 3D data serves as a crucial navigation map for FIB processing.

๐Ÿค– LLM Prompt Example: Comparing 3D Structure to Patent Drawings


# Role: 3D CT Data Analysis Expert
# Input: [A series of slice images from the 3D volume data]

# Analysis Requirements:
1. Identify and count the Through-Silicon Via (TSV) structures.
2. Analyze the die stack structure (number of layers, thickness, spacing).
3. Analyze the wire bonding/flip-chip bump pattern.
4. Compare the structural similarity with the patent drawings.
(Specifically, reference drawing: [Attach Patent Drawing])

# Target Structures:
- "8-layer stacked memory die"
- "Vertical through-electrode structure"
- "Symmetrical bonding pad layout"

Describe the analysis results in connection with the patent claims.
        

Step 3: Precision Sample Preparation - A Nanoscale Surgery

To directly observe the micro-circuitry inside the chip, the outer protective layers must be removed and the specific area of interest precisely exposed. Every action in this stage is irreversible, making it a high-stakes procedure akin to delicate surgery where evidence preservation is the top priority.

๐Ÿ’ก A Note on Evidence Integrity
Every step of the analysis must be conducted with the expectation of court submission. Adopting the concept of a Minimal Viable Evidence (MVE) package is critical. An MVE should include:
  • Original Sample Information: Photos of the original chip, serial numbers, and the SHA-256 hash if it's a file.
  • Chain of Custody Log: Model names of all equipment, software versions, and the exact commands and settings used.
  • Data Integrity: Hash values (SHA-256) of all raw data (images, logs, pcap files) must be recorded with UTC timestamps to prove they have not been altered.
  • Analyst's Declaration: A signed affidavit from the analyst attesting that all procedures were followed correctly.
This rigorous documentation ensures the credibility and reproducibility of the evidence.

3.1 Decapsulation

  • Purpose: To cleanly and safely expose the surface of the silicon die for analysis.
  • Principle: The Epoxy Molding Compound (EMC) protecting the chip is removed using methods such as chemical etching, laser ablation, or plasma etching. The best method is chosen based on the chip's characteristics.

๐Ÿค– LLM Prompt Example: Determining Optimal Process Conditions


# Role: Semiconductor Packaging Process Expert
# Task: Select a decapsulation method that minimizes damage

# Product Information:
- Package Type: [BGA/QFN/etc.]
- Wire Material: Pd-coated Cu wire (assumed)
- EMC Material: Epoxy Molding Compound
- Target Analysis Area: Metal interconnect layers on the die surface

# Technical Literature Search Request:
1. Find chemical decapsulation conditions that are non-corrosive to Cu wires.
2. Compare the pros and cons of plasma etching vs. chemical etching.
3. Recommend relevant process parameters (temperature, time, concentration).
4. For each method, assess the expected level of damage and its impact on analysis reliability.

Please provide answers based on the latest academic papers and technical notes.
        

3.2 FIB (Focused Ion Beam) Precision Cross-Sectioning

  • Purpose: To obtain a clean, flat cross-section suitable for SEM or TEM analysis, enabling accurate examination of material interfaces, cracks, metal layer thicknesses, and more.
  • Principle: This technique uses a highly focused beam of heavy ions, such as Gallium (Ga+), accelerated at high energy to mill away material from a specific point on the sample, atom by atom (a process called sputtering).
  • Results Interpretation: FIB is essential when a patent claim specifies a feature in a microscopic area, such as the ‘spacer structure between the gate and source/drain of a FinFET.’ It allows for the precise isolation and preparation of that exact location for analysis.

๐Ÿค– LLM Prompt Example: Drafting a FIB Milling Script


# Role: FIB Processing Optimization Expert
# Input: 3D CT coordinate data + target transistor location

# Task:
Draft a FIB milling script that meets the following conditions:
- Target Coordinates: X=1250 ยตm, Y=890 ยตm, Z=15 ยตm (relative to die surface)
- Target Structure: Gate cross-section of a FinFET transistor
- Required Resolution: <5 nm
- Milling Depth: Approx. 2 ยตm

# Script Requirements:
1. A multi-step approach for coarse and fine milling.
2. Optimized ion beam voltage/current conditions.
3. Logic for real-time SEM image feedback during milling.
4. Final polishing conditions to achieve atomic-level surface flatness.

# Output: A script for the FIB machine with detailed comments for each step.
        

Step 4: High-Resolution Structural & Compositional Analysis

This is the core of the reverse engineering process, where the prepared sample's cross-section is examined under high-magnification microscopes to directly verify the physical structures and material compositions specified in the patent claims. The images and data obtained here become the most direct and powerful evidence in the claim chart.

4.1 SEM/EDS Analysis

  • Purpose: To visually confirm nanoscale microstructures, measure critical dimensions like circuit line widths and thin-film thicknesses, and simultaneously analyze the elemental composition.
  • Principle: A SEM (Scanning Electron Microscope) scans the sample surface with an electron beam and detects secondary electrons to generate a high-resolution 3D topographical image. An EDS (Energy Dispersive X-ray Spectroscopy) detector, often attached to the SEM, analyzes the characteristic X-rays emitted from the sample when struck by the electron beam to identify the elements present and their relative amounts.
  • Results Interpretation: SEM images can be used to measure the fin height or gate length of a FinFET. EDS results are typically presented as a spectrum, which identifies elements by their characteristic energy peaks, and an elemental map, which visualizes the distribution of each element with different colors. For example, if a map of a gate structure shows a concentration of Hafnium (Hf) and Oxygen (O) in a specific layer, it provides strong evidence that the layer is HfO₂.

๐Ÿค– LLM Prompt Example: Comprehensive SEM/EDS Data Analysis


# Role: SEM/EDS Data Analyst
# Input: [SEM image + EDS elemental mapping data]

# Analysis Task:
1. Identify each layer of the High-K Metal Gate structure.
   - Measure the thickness of the gate dielectric (HfO₂).
   - Confirm the presence of the barrier metal layer (TiN).
   - Analyze the structure of the gate electrode (W).
2. Differentiate materials based on the Backscattered Electron (BSE) image contrast.
3. Interpret the quantitative results from the EDS analysis.
4. Evaluate the consistency with the patent claim.

# Patent Claim: "A transistor structure comprising a High-K dielectric layer with a thickness of 2-3nm and a metal gate electrode."

Objectively evaluate for potential infringement based on the measured values.
        

๐Ÿค– LLM Prompt Example: Automated Analysis of Large Image Sets


# Role: Pattern Recognition and Statistical Analysis Expert
# Input: [Folder containing 2000 SEM images]

# Automated Analysis Request:
1. Automatically identify FinFET patterns in each image.
2. Automatically measure the Gate Pitch and Fin Width for each identified FinFET.
3. Calculate the statistical distribution of the measured values (mean, standard deviation, min/max).
4. Detect and classify any anomalous patterns (defects).

# Target Accuracy: >95%
# Output: A Python pandas DataFrame and visualization charts.

Evaluate the results in relation to the patent claim for a "regular array of fin structures."
        

4.2 TEM Analysis

  • Purpose: To precisely measure the thickness of ultra-thin films at the atomic layer level, analyze the interface structure between different materials, and determine the material's crystalline structure (crystalline/amorphous).
  • Principle: Unlike SEM, a TEM (Transmission Electron Microscope) obtains an image by passing an electron beam *through* an extremely thin sample (typically under 100nm). The contrast in the resulting image is determined by the sample's density, thickness, and the degree of electron scattering and diffraction by its crystal structure.
  • Results Interpretation: TEM offers the highest spatial resolution, allowing direct observation of atomic columns. It can provide irrefutable proof for claims such as "a 2nm thick hafnium oxide layer formed on a silicon substrate." Furthermore, if features characteristic of a specific deposition method, like the excellent thickness uniformity and conformal coverage of Atomic Layer Deposition (ALD), are observed, it strongly supports the argument that said process was used.

๐Ÿค– LLM Prompt Example: TEM Lattice Image Analysis


# Role: TEM Lattice Fringe Analysis Expert
# Input: [High-Resolution TEM Image]

# Task:
1. Measure the lattice fringe spacing and identify the crystal structure via FFT analysis.
2. Analyze the characteristics of the interface between different materials.
3. Check for evidence of an Atomic Layer Deposition (ALD) process.
4. Differentiate between crystalline and amorphous regions.

# Analysis Tools:
- Fast Fourier Transform (FFT) analysis
- Lattice spacing measurement algorithm
- Interface roughness quantification

# Patent Relevance:
Substantiate the claim of a "uniform thin-film interface formed by atomic layer deposition" with evidence from the TEM image.

# Output: Image annotations + measurement data + interpretation report
        

Step 5: Specialized Analysis - Measuring the Invisible

This step analyzes the 'unseen' factors that determine the core electrical properties of a semiconductor, which cannot be observed with conventional electron microscopy. This provides direct evidence of 'how a device was designed to operate.'

5.1 SIMS (Secondary Ion Mass Spectrometry) Analysis

  • Purpose: To quantitatively measure the depth profile of dopants (e.g., Boron, Phosphorus), which are key elements determining the device's performance.
  • Principle: A primary ion beam continuously sputters the sample surface. The ejected secondary ions are then guided into a mass spectrometer, which separates and detects them to analyze elemental concentration by depth, down to the parts-per-billion (ppb) level.
  • Results Interpretation: The output is a log-linear graph with depth on the x-axis and concentration on the y-axis. This allows for precise determination of peak concentration, junction depth, and the overall shape of the doping profile. A patent claim for a "Lightly Doped Drain (LDD) structure" can be proven by showing a SIMS profile with a specific graded concentration near the source/drain regions.

๐Ÿค– LLM Prompt Example: Interpreting SIMS Data


# Role: SIMS Data Interpretation Specialist
# Input: [SIMS depth profile graph]

# Analysis Requirements:
1. Accurately identify the p-type/n-type doping junction location.
2. Determine if a Lightly Doped Drain (LDD) structure exists.
3. Calculate the dopant concentration gradient.
4. Assess the need for matrix effect correction.

# Patent Claim: "A transistor comprising a lightly doped region between the source/drain and the channel."

# From the graph analysis, determine:
- Dopant concentration in the LDD region: ___ atoms/cm³
- Length of the LDD: ___ nm
- Concentration gradient: ___ atoms/cm³/nm

Provide a comprehensive assessment, including measurement uncertainty and correction methods.
        

5.2 EBSD (Electron Backscatter Diffraction) Analysis

  • Purpose: To analyze the microstructure of polycrystalline materials like metal interconnects, determining the size, shape, and orientation distribution of crystal grains.
  • Principle: Performed within an SEM, an electron beam hits a crystalline sample, causing electrons to diffract off the atomic lattice. Some of these backscattered electrons form a distinct geometric pattern known as a Kikuchi pattern, which contains unique information about the crystal structure and orientation at that point.
  • Results Interpretation: The primary output is a crystal Orientation Map, where each grain is colored according to its crystallographic orientation. If most grains share a similar color, it indicates the film has a preferred orientation or texture. This can be used to prove a claim like "a copper interconnect with a preferred (111) orientation for enhanced electrical reliability."

๐Ÿค– LLM Prompt Example: Generating an EBSD Data Analysis Script


# Role: EBSD Data Processing and Visualization Expert
# Task: Write a script for statistical analysis of crystal orientation.

# Requirements:
1. Extract crystal grains with (111) orientation from raw EBSD data.
2. Calculate the percentage of the total area occupied by (111) oriented grains.
3. Generate a histogram of grain size distribution.
4. Visualize the orientation map.

# Input Data: EBSD file in .ang format
# Target Output:
- Statistical report (PDF)
- High-resolution orientation map image
- Analysis results in a CSV file

# Patent Relevance: Provide quantitative data to substantiate the claim of "(111) preferred orientation of copper interconnects."

Write a complete Python script and add comments to major functions.
        

Step 6: LLM-Powered Claim Chart Drafting Strategy

All reverse engineering efforts culminate in the creation of a legally persuasive claim chart. A well-crafted claim chart translates complex technical data into a clear, logical argument that a judge or jury can understand.

๐Ÿ’ก Key Strategies for a Strong Claim Chart
  • Select the Best Evidence: Use the most direct and irrefutable data to prove each claim element (e.g., TEM images for nanometer-scale thickness, EDS data for material composition).
  • Clear Annotation: Use arrows, labels, and scale bars on analytical images to explicitly show where the claim elements are met. Leave no room for interpretation.
  • Objective and Factual Narration: Describe the evidence factually, such as, "The TEM image shows a layer with a thickness of 2.1 nm." Avoid subjective or conclusive language like, "The TEM image clearly proves infringement." Argumentation is the attorney's role; the claim chart is the collection of facts supporting that argument.

๐Ÿค– LLM Prompt Example 6.1: Automating Evidence-to-Claim Mapping


# Role: Patent Claim Chart Specialist
# Task: Convert technical evidence into legal document format.

# Input Data:
- Patent Claim: "A transistor having a plurality of fin structures formed on a substrate, wherein each fin has a width of 7nm or less."
- Analytical Evidence:
  - SEM Measurements: Average fin width of 6.2 nm ± 0.3 nm (n=500).
  - Statistical Distribution: 99.2% of fins are 7nm or less.
  - Image Evidence: [SEM Image A, B, C]

# Requirements:
1. Use objective, fact-based language.
2. Include measurement uncertainty.
3. Specify statistical confidence.
4. Adhere to a formal legal tone and style.

# Output Format:
"The accused product meets the 'fin width of 7nm or less' element of the claim as follows: [Evidence-based description]"

Exclude any emotional or speculative language; state only the pure facts.
        

๐Ÿค– LLM Prompt Example 6.2: Auto-generating Image Annotations and Descriptions


# Role: Technical Image Annotation Specialist
# Input: [SEM-EDS Elemental Mapping Image]

# Task:
Identify the distribution areas of the following elements and link them to the patented structure:
- Hf (Hafnium): Gate dielectric
- Ti (Titanium): Barrier metal layer
- W (Tungsten): Gate electrode
- O (Oxygen): Oxide layer

# Output Requirements:
1. Color-coded annotations for each elemental region.
2. Indication lines for measuring layer thickness.
3. Explanation of the structural correspondence with the patent drawings.
4. A high-quality image layout suitable for court submission.

# Image Caption: "Confirmation of High-K Metal Gate structure via EDS elemental mapping. Physical evidence for claim element (c) of the patent."
        

Step 7: Expert Verification and Legal Validation

Any output generated by an LLM must be verified by a human expert. Furthermore, systematic evidence management is essential to ensure the credibility of the entire analysis process.

7.1 Cross-Verifying LLM Outputs

It's crucial not to rely on a single LLM. Using multiple models (e.g., Claude, ChatGPT, Gemini) to cross-verify results can help filter out biases or errors specific to one model.

๐Ÿค– LLM Prompt Example: Cross-Verification Request


# Role: Analysis Results Cross-Verifier
# Task: Verify the technical accuracy of results generated by another LLM.

# Targets for Verification:
1. Draft of a claim chart written by Claude.
2. SEM image interpretation analyzed by ChatGPT.
3. Image annotations generated by Gemini.

# Cross-Verification Method:
- Confirm consistency between interpretation and raw data.
- Perform an independent re-analysis using a different LLM.
- Detect technical errors and logical fallacies.
- Review the accuracy of legal terminology.

# Output: Verification report + recommended revisions.
        

7.2 Assembling the MVE (Minimal Viable Evidence) Package

In litigation, the integrity and chain of custody of evidence are paramount. The Minimal Viable Evidence (MVE) package is a systematic collection of documents that records and preserves every step of the analysis to establish its legal admissibility. An LLM can be used to generate and manage a tailored MVE checklist for each project.

๐Ÿค– LLM Prompt Example: Generating an MVE Checklist


# Role: Forensic Evidence Management Specialist
# Task: Generate a checklist of MVE components.

# Analysis Project Information:
- Project Name: [Project Name]
- Analysis Period: [Start Date] to [End Date]

# Requirements:
Generate a detailed MVE checklist including the items below, and specify the required documents and retention period for each.
- Original sample information and hash values
- Calibration certificates for all analysis equipment
- Raw data files and backup locations
- Full LLM interaction logs (prompts and responses)
- Analyst identity verification
- Record of analysis environment and conditions (temperature, humidity, etc.)
- Certificate of compliance with quality management standards
        

Frequently Asked Questions (FAQ)

Q: Is there a risk of the LLM misinterpreting analysis results?
A: Absolutely. LLMs can be prone to ‘hallucinations’ or may miss subtle technical nuances. Therefore, any LLM-generated response must be cross-verified by a human expert against the original data (e.g., SEM/TEM images, numerical data). It's critical to remember that the LLM is a tool to assist the analyst, not the final decision-maker.
Q: How much does semiconductor reverse engineering typically cost?
A: Depending on the depth and scope of the analysis, costs can range from tens of thousands to hundreds of thousands of dollars. Atomic-level analyses like TEM and SIMS are particularly expensive due to the required equipment and specialized personnel. Therefore, it's vital to assess the likelihood of finding a ‘smoking gun’ with preliminary, less expensive methods (like non-destructive and SEM analysis) and to plan the analysis based on a cost-benefit evaluation.
Q: Our company doesn't have the necessary equipment. How can we conduct RE?
A: Most companies outsource semiconductor RE to specialized third-party labs. The key is to clearly define, manage, and oversee the analysis: what to analyze, in what order, and under what conditions. The workflow and LLM strategies in this guide can be invaluable for defining technical requirements and effectively reviewing the results when collaborating with external labs.
Q: If the chip is damaged during analysis, does the evidence lose its validity?
A: This is a critical point. It's precisely why a Minimal Viable Evidence (MVE) package and meticulous documentation are necessary. Before analysis, the state of the original sample should be documented with photos and videos. Every step of the analysis must be recorded, and all outputs (images, data) should be timestamped and hashed to prove the chain of custody. This process ensures that even destructive analysis can be accepted as admissible evidence in court.
Q: How can I write the most effective LLM prompts?
A: Great prompts have three key elements: a clearly defined 'role,' specific 'context,' and a request for a 'structured output format.' For instance, instead of just saying, “Analyze this image,” a more effective prompt would be, “You are a materials science Ph.D. Analyze this SEM image to measure the gate length of the FinFET. Report the result to two decimal places and mark the measurement location on the image.” Being specific is always better.

Conclusion: The Optimal Synergy of Human Experts and AI

Leveraging LLMs for semiconductor reverse engineering is an innovative methodology that goes beyond simple efficiency improvements to achieve a quantum leap in analytical quality and the strength of legal evidence. However, the most important principle to remember is that the ultimate responsibility for all technical interpretations and legal judgments still rests with human experts.

Core Principles for Successful LLM Integration
  1. Clear Division of Labor: LLMs handle data processing and drafting; humans handle verification and final judgment.
  2. Multi-Model Approach: Strategically use different LLMs based on their strengths for specific tasks.
  3. Rigorous Verification: Always cross-reference LLM outputs with the original source data.
  4. Legal Safeguards: Ensure evidence integrity by compiling a comprehensive MVE.

Ultimately, the success of this process depends on close collaboration between technical and legal experts. The legal team must clearly define the key elements of the patent claims, and the technical team must present analytical results as clear, objective data linked to those legal issues. When scientific evidence and legal logic are combined in this way, data from the lab can become the most powerful and persuasive weapon in the courtroom.
