# Finding: When Goldberg First Used His Name Instead of Litman on Filings

**Goal:** Identify the earliest patent/filing where Joshua Goldberg's name replaced Richard Litman's (e.g., on Line 74, assignments, etc.).

---

## Summary of Current Evidence

### Assignments
- **All reviewed assignments** show **Litman** as correspondent and **Goldberg** as submitter.
- **None** show Goldberg as correspondent — so we have no assignment-based "first date" for Goldberg-as-correspondent.

### KFU 2024 Patents
- **467** KFU patents have Litman on Line 74 (confirmed from `kfu_2024_litman_attorney_patents.csv`).
- **~164** KFU patents (631 − 467) would have Goldberg or another attorney on Line 74.
- We have the Litman list but **not** a curated list of KFU patents with Goldberg on Line 74.

### goldberg_post_2024-07-21_patents.csv
- Contains ~1,162 patents; filename suggests search for patents **after 7/21/2024**.
- **Earliest 2024 date in file: 2024-07-23** (e.g., 12041933, 12042196, 12043608, 12043609, etc.).
- File has **no assignee column** — cannot filter for KFU.
- **9 patents** appear in both the KFU Litman list and this Goldberg file (possible co-attorney or different search criteria).
- **Limitation:** If the search was limited to post-7/21/2024, we cannot infer the true earliest Goldberg patent from this file alone.

## How to Find the Answer

### 1. USPTO Patent Public Search

**URL:** https://ppubs.uspto.gov/pubwebapp/

**Query for earliest KFU patent with Goldberg on Line 74:**
```
("King Faisal University").AS. AND (Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101
```

- Export results, sort by issue date ascending.
- The **first patent** in the list = earliest KFU patent with Goldberg on Line 74.

**Query for earliest Goldberg patent (any assignee):**
```
(Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101
```

- Export, sort by issue date ascending.
- First patent = earliest patent with Goldberg on Line 74.

### 3. USPTO Assignment Center

- Search for assignments where the **correspondent block** shows Goldberg instead of Litman.
- If the interface supports correspondent-name search, look for "Goldberg" or "Joshua Goldberg".
- Earliest such assignment = first filing where Goldberg replaced Litman as correspondent.

## Confirmed Finding (USPTO Patent Public Search)

**Earliest KFU patent with Goldberg on Line 74: US 11,858,934 B1 — 2024-01-02**

| Field | Value |
|-------|-------|
| Patent | US 11,858,934 B1 |
| Issue Date | 2024-01-02 |
| Title | Substituted Pyrido[4',3':5,6]pyrimido[1,2-a]indoles As CK2 Inhibitors |
| Assignee | King Faisal University |
| Application | 18/223,002 |
| Date Filed | 2023-07-17 |
| Inventors | Tratrat; Christophe, Haroun; Michelyne (Al-Ahsa, SA) |

**Query used:** `("King Faisal University").AS. AND (Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101` — 212 results.

**Full export:** `output/KFU_GOLDBERG_PATENTS_212_RESULTS.csv` (from USPTO Patent Public Search, Mar 15 2026). Export sorted newest-first; row 183 = earliest by issue date. US 11,858,934 B1 (2024-01-02) is the only patent with **Date Published** in January 2024 — definitively the earliest KFU patent with Goldberg on Line 74.

**Significance:** Goldberg's name appears on Line 74 of this patent. Per the Line 74 control inference, this demonstrates he had control over the attorney designation by **January 2, 2024** — the earliest confirmed date for KFU.

### All-assignees search (Goldberg + Joshua, any client)

**Query:** `(Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101` — 712 results total (per USPTO).

**Export:** `output/GOLDBERG_ALL_ASSIGNEES_500_RESULTS.csv` — first 500 results (newest-first). Earliest in this export: 2024-09-10. No January 2024 patents in this export (they would be in the oldest 212 when sorted ascending).

**Conclusion:** US 11,858,934 B1 (2024-01-02) is likely the earliest Goldberg patent for **any** assignee as well — KFU was his first major client to show Goldberg on Line 74. To confirm, sort the 712 results by Date Publish ascending and export; the first row would be definitive.

### Search #2: Goldberg patents after 6/15/2025 (transition evidence)

**Query:** `(Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20250615`

**Finding:** From the all-assignees export (500 newest results), **158 patents** have Date Published ≥ 2025-06-15. Earliest in subset: **2025-06-17**.

**Export:** `output/GOLDBERG_POST_615_2025.csv` — 158 patents with Goldberg on Line 74 issued after the "late-period" cutoff. Assignees include KFU, KSU, Kuwait University, UAEU, BOE Technology, Verified Genius, and others.

**Significance:** Goldberg continued as attorney of record well after 6/15/2025 — supports the transition narrative (Goldberg taking over where Litman left off).

### Search #3: Litman + Goldberg overlap (post-7/21/24) — Confirmed

**Query:** `(Litman).ATTY. AND (Richard).ATTY. AND (Goldberg).ATTY. AND @pd>=20240721`

**Result:** 11 patents (USPTO export). Matches our 12 overlap exhibit set (one may be a family/duplicate).

**Export:** `output/LITMAN_GOLDBERG_OVERLAP_POST_721_2024.csv`

**Assignees:** King Faisal University (8), King Saud University (2), Kuwait Institute for Scientific Research (1). Date range: 2024-07-23 to 2025-01-14.

### Search #4: Litman + Goldberg overlap (post-6/15/2025) — 0 results

**Query:** `(Litman).ATTY. AND (Goldberg).ATTY. AND @pd>=20250615`

**Result:** No patents found. Consistent with Litman-only post-6/15/2025 returning 0 — no patents list Litman as attorney after that date, so no overlap with Goldberg.

## Provisional Finding (from goldberg_post_2024-07-21_patents.csv)

**Earliest 2024 patent in that file: 2024-07-23**

Examples:
- 12041933 — N-(pyrimidin-2-ylcarbamothioyl) benzamide...
- 12043608 — 2-(Benzo[b]thiophen-3-yl)-1-butyl-4,5-diphenyl-1H-imidazole...
- 12043609 — 6′(4-methoxyphenyl)-2′-alkoxy-3,4′-bipyridine-3′-carbonitrile...

**Caveat:** The file may be limited to post-7/21/2024. If Goldberg started earlier (e.g., Jan–Jun 2024), this would not capture it. Run the PatentsView script or USPTO query above to confirm.

## How to Hunt Down the Earliest Date

### Step 1: USPTO Patent Public Search (No API Key Required)

1. Go to **https://ppubs.uspto.gov/pubwebapp/**
2. Select database **USPAT** (granted patents)
3. Run one or both queries below

### Step 2: Queries to Run

**KFU-specific (earliest KFU patent with Goldberg on Line 74):**
```
("King Faisal University").AS. AND (Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101
```
- Returns 212 results (as of March 2025)
- Sort results by **Date Publish ascending** (click column header)
- First row = earliest KFU patent with Goldberg on Line 74

**All assignees (earliest patent with Goldberg on Line 74, any client):**
```
(Goldberg).ATTY. AND (Joshua).ATTY. AND @pd>=20240101
```
- Returns 712 results (as of March 2025)
- Sort by **Date Publish ascending**
- First row = earliest patent with Goldberg on Line 74

### Step 3: Record the Answer

- Note the **patent number** and **issue date** of the first result
- Update this document with the confirmed earliest date
- Add to `output/LINE_74_CONTROL_INFERENCE_MEMO.md` as an example

### Step 4: Why This Matters

The earliest date establishes **when Goldberg first began using his name instead of Litman** on patent front pages. Combined with the Line 74 control inference (see `LINE_74_CONTROL_INFERENCE_MEMO.md`), it supports the argument that Goldberg had control over attorney designation throughout the transition period.

## Next Steps (After Manual Search)

1. **Run** the USPTO queries above and record the earliest patent.
2. **Update** this document with the confirmed earliest date.
3. **Optional:** Re-run the USPTO Patent Public Search query periodically for updated results.
