Patent IPC Classification

Dataset Description

This dataset is part of PatenTEB, a comprehensive benchmark for evaluating text embedding models on patent-specific tasks. PatenTEB comprises 15 tasks across retrieval, classification, paraphrase detection, and clustering, with 2.06 million examples designed to reflect real-world patent analysis workflows.

Task Details

• Task Name: class_text2ipc3
• Task Type: Classification
• Test Samples: 18,727
• Training Samples: 30,000 (20% training subset for evaluation)

Multi-class classification of patent families into 109 IPC3 (International Patent Classification at 3-digit level) technological domains. IPC3 provides balanced granularity between top-level sections and full classifications, covering diverse technologies from pharmaceuticals to semiconductors.

Splits:

• test: Full test set for evaluation
• train: 20% subset of training data used during evaluation

Columns:

Evaluation Metrics

This task uses Macro-F1 as the primary metric, computed by averaging per-class F1 scores. Models are evaluated using a 20% training subset with logistic regression classifiers trained on embeddings.

Usage

Load Dataset

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("datalyes/{task_name}")

# Access test split
test_data = dataset['test']

# Access 20% training subset (for classification tasks)
train_data = dataset['train']

Use with Sentence Transformers

from sentence_transformers import SentenceTransformer

# Load a patent-specialized model
model = SentenceTransformer("datalyes/patembed-base")

# Encode patent texts
embeddings = model.encode(test_data['text'])

Integrate with MTEB

This dataset is designed to be integrated with the MTEB (Massive Text Embedding Benchmark) framework. Integration with MTEB is in progress and will be available once the corresponding pull requests are accepted.

Benchmark Context

This dataset is part of a larger benchmark suite:

Benchmark Component	Description
PatenTEB	15 tasks covering retrieval, classification, paraphrase, clustering
Test Data (Released)	319,320 examples across all 15 tasks
Training/Validation Data	1.74 million examples (planned for future release)
Total Dataset Size	2.06 million annotated instances

Note: Currently, only the test split is publicly available. Training and validation data release is planned for a future date.

All 15 Tasks (NEW to MTEB):

• 3 classification tasks: Bloom timing, NLI directionality, IPC3 classification
• 2 clustering tasks: IPC-based, Inventor-based
• 8 retrieval tasks: 3 symmetric (IN/MIXED/OUT domain) + 5 asymmetric (fragment-to-full)
• 2 paraphrase tasks: Problem and solution paraphrase detection

MTEB Integration: Upcoming (PR in progress)
