Imagine: a portfolio of 500+ patents, weekly manual monitoring of USPTO and FIPS, missed renewal dates. An AI system for IP management automates this mess. We build solutions based on LLMs, vector databases, and MLOps infrastructure that search for analogs, track infringements, and value the portfolio. One client cut patent search time from 40 hours to 4 after deployment — 80% savings. Manual monitoring costs dropped thousands of dollars monthly. By our estimates, a typical 500-patent portfolio requires annual monitoring costs in the hundreds of thousands of dollars; automation reduces that to tens of thousands. The project cost is calculated individually.
How AI Finds Similar Patents?
Key component is semantic search. Convert patent text into an embedding (model text-embedding-ada-002, 1536 dimensions) and search for nearest neighbors in a vector database (Qdrant, ChromaDB). But embedding alone is not enough — we add a cross-encoder for re-ranking: prior art search accuracy reaches 95%. For query generation, we use an LLM with a few-shot prompt: "Find patents describing a method \"{entity}\" and device \"{element}\".
Compare to manual search: AI processes 20,000 patents per minute, while a specialist does at most 50 per day. Such semantic search is 3 times more accurate than traditional text-based search.
Why Is Trademark Monitoring a Bottleneck?
Manually checking millions of products on marketplaces is impossible. AI tracks visual similarity via convolutional networks (ResNet-50 fine-tuned on logos) and textual similarity via BERT. The system scans Wildberries, Ozon, Avito daily. When similarity score >0.8 — generates an alert. Plus monitoring new applications in FIPS: if someone tries to register a similar mark, you find out first. AI monitoring is 20 times faster than manual.
More on visual comparison
For image comparison we use cosine similarity of embeddings. We fine-tune the model on your portfolio — accuracy reaches 97%.

Key System Modules
-
IP Object Registry — unified database of all IP objects with metadata, deadlines, statuses.
-
Infringement Monitoring — automatic monitoring of the internet, marketplaces, registers for unauthorized brand and technology use.
-
Patent Analysis — monitor new patent applications of competitors, prior art search, patentability assessment.
-
Prosecution Automation — renewal deadlines, international applications, correspondence with patent offices.
Typical Implementation Mistakes
- Choosing an embedding model without considering multilingualism: for FIPS you need a model that understands Russian.
- Ignoring data quality: incomplete registries lead to missed infringements.
- Lack of MLOps pipeline: a model without drift monitoring quickly loses accuracy.
How AI Values a Patent Portfolio?
The model is trained on historical data: citation count, patent age, CPC/IPC scope breadth, licensing revenue. We use Gradient Boosting or a neural network for regression. Result: market value for M&A and IAS 38 reporting. Order an audit of your current IP portfolio — we will show where hidden reserves lie.
Trademark Monitoring
class TrademarkMonitor:
def monitor_infringements(self, trademark: Trademark) -> list[InfringementAlert]:
alerts = []
# Search on marketplaces
for marketplace in ["wildberries", "ozon", "avito"]:
results = marketplace_api.search(trademark.name)
for item in results:
similarity = self.compute_visual_similarity(item.image, trademark.logo)
text_similarity = self.compute_text_similarity(item.title, trademark.name)
if similarity > 0.8 or text_similarity > 0.85:
alerts.append(InfringementAlert(
source=marketplace,
url=item.url,
similarity_score=max(similarity, text_similarity),
type="counterfeiting"
))
# Search in FIPS registers (new similar trademark applications)
new_applications = fips_api.get_new_applications(
nice_classes=trademark.nice_classes,
date_from=self.last_check
)
for app in new_applications:
if self.compute_text_similarity(app.name, trademark.name) > 0.7:
alerts.append(InfringementAlert(
source="FIPS",
url=app.url,
type="confusingly_similar_registration"
))
return alerts
Patent Landscape
Competitor patent landscape analysis:
- Monitor new patent applications (USPTO, EPO, FIPS, CNIPA)
- Classify by technological areas (CPC, IPC codes)
- Visualize patent landscape (technology × company × time)
- Analyze "white spaces" — technological areas without competitor patents
APIs: Google Patents API, Lens.org API (free), EPO Open Patent Services.
Prior Art Search
When developing a new technology: search for prior art (existing patents and publications) before filing:
def search_prior_art(invention_description: str) -> PriorArtReport:
# Generate search queries via LLM
queries = llm.generate_patent_queries(invention_description)
# Search patent databases
patents = patent_db.semantic_search(invention_description, top_k=20)
# Assess relevance
relevant = [p for p in patents if cross_encoder.score(invention_description, p.abstract) > 0.6]
return PriorArtReport(
relevant_patents=relevant,
novelty_assessment=llm.assess_novelty(invention_description, relevant),
patentability_risks=llm.identify_risks(relevant)
)

NLP Development: Text Classification, NER, Embeddings, and Information Extraction
We often receive a task: process 50,000 support tickets — currently all manual. Dataset — 3,000 labeled examples, 12 categories, imbalance: one category occupies 40% of the sample, three at 1-2% each. Baseline accuracy — 78%. Sounds decent until you look at recall for rare classes: 0.31, 0.44, 0.28. These classes — complaints and churn threats — are most important to the business.
This is a typical NLP development project. The problem is not the algorithm but that accuracy is the wrong metric. Our experience across 30+ projects shows: we start by analyzing business metrics and only then choose the model.
Why accuracy is not the right metric for rare classes?
Accuracy ignores imbalance. If the "churn" class appears in 2% of cases, the model can predict "all good" and get 98% accuracy — but the business loses clients. Solution: F1 macro (averaged over all classes) or weighted F1. For NER — strict entity F1 (exact matches only). We guarantee: after choosing the correct metric, model quality becomes measurable and predictable.
Text Classification: From BERT to Distillation
BERT-like models are the standard for classification. ruBERT-base or ruBERT-large from DeepPavlov for Russian. multilingual-e5-large — for multiple languages in one pipeline. XLM-RoBERTa-large — a strong multilingual backbone.
Fine-tuning for classification: add a classification head on top of the [CLS] token, train for 3-5 epochs with lr=2e-5, weight decay=0.01. For imbalance — weighted CrossEntropyLoss or focal loss with gamma=2.0. Contact us — we will show a code snippet.
Imbalance case study. Dataset — 3,000 examples, imbalance 1:20. Solution: class_weight via sklearn + CrossEntropyLoss. Additionally — augmentation of rare classes via backtranslation (ru→en→ru through MarianMT). Recall for rare classes rose from 0.31 to 0.67 with a slight drop in accuracy (76%→74%). Full NLP development end-to-end took 3 weeks.
Distillation for production. BERT-large gives F1 0.89, but inference on CPU — 180ms. Distillation into DistilBERT or ruBERT-tiny2 reduces latency to 25ms with F1 0.84. Export to ONNX Runtime provides an additional 1.5-2x speedup. DistilBERT achieves 7x lower latency than BERT-large with only a 5% drop in macro F1 – a typical production trade-off.

How to choose between BERT and LLM for your task?
For most classification and extraction tasks, BERT-sized models offer the best trade-off between cost and performance. Shift to LLMs only when the task demands generation, complex reasoning, or zero-shot generalization.
NER: Named Entity Recognition
NER — extracting persons, organizations, locations, dates, amounts, document numbers. For general categories (PER, ORG, LOC), pre-trained models work well. For specialized ones (medical terms, legal concepts) — fine-tuning is needed.
Data annotation. The main cost of an NER project. For a quality model — 500-2,000 labeled sentences per entity type. Tools: Label Studio (open source) or Prodigy (by spaCy creators). IOB2 format — standard.
Architecture. Token classification on top of BERT: each token gets a label (B-PER, I-PER, O). spaCy 3.x with transformer pipeline — a convenient production choice.
Nested entities. Standard IOB models cannot handle nested entities (organization inside an address). For such tasks — span-based NER: SpanBERT or SpERT. More complex but correct.
Post-processing is mandatory. The model predicts tokens — normalized entities are needed. Date — dateparser. Amounts — regex + validation. Names — deduplication via rapidfuzz. Included in our standard delivery.
Sentiment Analysis and Opinion Mining
Binary classification positive/negative works out of the box with BERT. Complexity — aspect-based sentiment analysis (ABSA): "the restaurant has good food but terrible service." For ABSA: aspect extraction (NER) + sentiment per aspect. Joint models BERT-for-ABSA — quality on Russian data is lower due to dataset scarcity. RuSentiment, SentiRuEval — main resources.
For production with simple positive/negative/neutral: distil models are enough. Three classes, balanced dataset, 2,000+ examples — F1 macro 0.82-0.87 in 1-2 days.
Text Summarization
Extractive summarization (select sentences) — TextRank or BM25 without training. Fast, no hallucinations. Good for long documents.
Abstractive (generates new text) — seq2seq: mT5, mBART, FRED-T5, ruT5-large. For production via LLM API (GPT-4, Claude) — often the best cost/quality/speed trade-off.
Embeddings: Vector Representations of Text
Embeddings are the foundation of semantic search, deduplication, clustering, RAG. Quality critically affects downstream tasks.
Models. E5-large-v2, BGE-M3, multilingual-e5-large — strong multilingual embedders. sentence-transformers/paraphrase-multilingual-mpnet-base-v2 — fast option. For Russian: ru-en-RoSBERTa (Skoltech) performs well on semantic textual similarity.
Embedding quality evaluation uses the MTEB benchmark as standard. But top results on MTEB don't guarantee success on a domain dataset — we build domain-specific eval.
Fine-tuning embeddings. If standard models don't give the required Recall@k — contrastive learning on domain pairs with MultipleNegativesRankingLoss. How to perform this for domain data:
- Collect 500–2,000 semantically similar pairs from your domain.
- Apply MultipleNegativesRankingLoss with a batch size of 32–64.
- Train for 1–3 epochs using AdamW (lr=2e-5).
- Evaluate Recall@k on a held-out domain test set.
This approach yields a 5–15% improvement in Recall@k in practice.
Dimensionality and storage. E5-large: 1024 dim, float32 — 4KB per vector. For 10M documents — 40GB. Quantization int8 reduces to 10GB. FAISS IVF_PQ — more compact but with losses. Included in our deployment recommendations.
Information Extraction
Structured extraction is a frequent task. Examples: key contract terms, technical characteristics, dates and amounts from invoices.
- Regex + rule-based. For INN, OGRN, amounts, dates — more reliable than neural networks. No data required.
- NER + post-processing. For variable formats.
- LLM with structured output. GPT‑4 / Claude with JSON schema — for complex documents. Cost: minimal per document. For 10k+ documents/day — we calculate the economics.
We guarantee a hybrid: regex/NER for typical fields + LLM for edge cases. Our guarantee is backed by years of production experience and more than 30 projects.
