# Power of Attorney (POA) Extraction Guide

**Purpose:** Determine who is listed as attorney and who signed on each POA. If Litman appears on later POAs than the original, that could indicate when his name was added.

## 1. POA PDFs

All POA PDFs have been downloaded and are available in `evidence/poa/`. Manifest: `evidence/poa/POA_MANIFEST.txt`.

## 2. What to Look For in Each PDF

| Field | Why it matters |
|-------|----------------|
| **Attorney(s) named** | Who is authorized to represent the applicant? Litman, Goldberg, others? |
| **Signatory** | Who signed the POA? Applicant or firm representative? |
| **Date signed** | When was authority granted? Compare to application filing date. |
| **Filing date (if shown)** | When did USPTO receive it? |

## 3. Exemplar Patents — Expected POAs

| Patent | Application | POA date(s) from IFW |
|--------|-------------|----------------------|
| 11,881,807 | 18/215,352 | 2023-06-29 (2 POA docs) |
| 11,932,607 | 18/384,685 | 2023-10-30 |
| 11,976,365 | 18/122,396 | 2023-03-16 |
| 11,980,937 | 18/392,663 | 2023-12-21 |

**Note:** 11,881,807 has two POA documents on the same date — may be different forms or amendments. Review both.

## 4. Recording Your Findings

Edit `evidence/poa/POA_EXTRACTION_RESULTS.csv` (columns):

| patent | application | poa_date | attorneys_listed | signatory | notes |
|--------|--------------|----------|------------------|-----------|-------|
| 11881807 | 18215352 | 2023-06-29 | Litman, Goldberg, ... | [name] | ... |

---

## 5. Interpretation

- **Litman on original POA** → He was authorized from the start for that application.
- **Litman on later POA only** → Suggests he was added after initial filing; supports "when was it changed" inquiry.
- **Goldberg as signatory** → Firm control; Goldberg submitting while Litman listed supports transition narrative.

## 6. OCR Extraction Results (Completed)

Automated OCR extraction populated `evidence/poa/POA_EXTRACTION_RESULTS.csv`:

| Patent | Form | Signatory | Note |
|--------|------|-----------|------|
| 11,881,807 | 82B (Applicant POA) | Applicant (King Faisal University) | Attorneys via Customer Number 37833 |
| 11,881,807 | 82A (Transmittal) | **Joshua B. Goldberg** | Patent Practitioner signatory |
| 11,932,607 | 82B | **Joshua B. Goldberg** | |
| 11,976,365 | 82B | **Joshua B. Goldberg** | |
| 11,980,937 | 82B | **Joshua B. Goldberg** | |

**Finding:** POA forms use Customer Number 37833 — individual attorneys (Litman, Goldberg) are not named on the form. Goldberg signed as Patent Practitioner on 4 of 5 documents. Supports firm control / transition narrative.
