### Overview
TSDR enables programmatic retrieval of trademark case status documents and information.
**API Version:** v1.0

```
### Endpoints
#### Get Trademark Status by Serial Number
```
GET /ts/cd/casedocs/sn{serial_number}/info.json
```
**Example:**
```bash
curl -H "X-Api-Key: YOUR_KEY" \
"https://tsdrapi.uspto.gov/ts/cd/casedocs/sn87654321/info.json"
```

### Python Example
```python
import requests
import xml.etree.ElementTree as ET
def search_trademark_assignments(registration_number, api_key):
"""Search assignments for a trademark registration."""
url = f"https://assignment-api.uspto.gov/trademark/v1.4/assignment/application/{registration_number}"
headers = {"X-Api-Key": api_key}
response = requests.get(url, headers=headers)
if response.status_code == 200:
return response.text # Returns XML
else:
raise Exception(f"API error: {response.status_code}")
# Usage
xml_data = search_trademark_assignments("5678901", "YOUR_API_KEY")
root = ET.fromstring(xml_data)
for assignment in root.findall('.//assignment'):
reel_frame = assignment.find('reelFrame').text
recorded_date = assignment.find('recordedDate').text
conveyance = assignment.find('conveyanceText').text
assignor = assignment.find('.//assignor/name').text
assignee = assignment.find('.//assignee/name').text
print(f"{recorded_date}: {assignor} -> {assignee}")
print(f" Type: {conveyance}")
print(f" Reel/Frame: {reel_frame}\n")
```
## Use Cases
### 1. Monitor Trademark Status
Check status of pending applications or registrations:
```python
def check_trademark_health(serial_number, api_key):
"""Check if trademark needs attention."""
data = get_trademark_status(serial_number, api_key)
tm = data['TradeMarkAppln']
status = tm['MarkCurrentStatusExternalDescriptionText']
alerts = []
if 'ABANDON' in status:
alerts.append("⚠️ ABANDONED")
elif 'PUBLISHED' in status:
alerts.append("📢 In opposition period")
elif 'SUSPENDED' in status:
alerts.append("⏸️ Examination suspended")
elif 'REGISTERED' in status:
alerts.append("✅ Active")
return alerts
```
### 2. Track Ownership Changes
Monitor assignment records for ownership changes:
```python
def get_current_owner(registration_number, api_key):
"""Find current trademark owner from assignment records."""
xml_data = search_trademark_assignments(registration_number, api_key)
root = ET.fromstring(xml_data)
assignments = []
for assignment in root.findall('.//assignment'):
date = assignment.find('recordedDate').text
assignee = assignment.find('.//assignee/name').text
assignments.append((date, assignee))
# Most recent assignment
if assignments:
assignments.sort(reverse=True)
return assignments[0][1]
return None
```
### 3. Portfolio Management
Analyze trademark portfolio:
```python
def analyze_portfolio(serial_numbers, api_key):
"""Analyze status of multiple trademarks."""
results = {
'active': 0,
'pending': 0,
'abandoned': 0,
'expired': 0
}
for sn in serial_numbers:
data = get_trademark_status(sn, api_key)
status = data['TradeMarkAppln']['MarkCurrentStatusExternalDescriptionText']
if 'REGISTERED' in status:
results['active'] += 1
elif 'PENDING' in status or 'PUBLISHED' in status:
results['pending'] += 1
elif 'ABANDON' in status:
results['abandoned'] += 1
elif 'EXPIRED' in status or 'CANCELLED' in status:
results['expired'] += 1
return results
```
## Rate Limits and Best Practices
1. **Respect rate limits** - Implement retry logic with exponential backoff
2. **Cache responses** - Trademark data changes infrequently
3. **Batch processing** - Spread requests over time for large portfolios
4. **Error handling** - Handle missing data gracefully (not all marks have all fields)
5. **Data validation** - Verify serial/registration numbers before API calls
## Integration with Other Data
Combine trademark data with other sources:
- **TSDR + Assignment** - Current status + ownership history
- **Multiple marks** - Analyze related marks in a family
- **Patent data** - Cross-reference IP portfolio
