+# Patent Boundary Notice
+
+## Scope
+
+The retokenization pipeline (`retokenize_scylla.py`) included in this repository converts
+SentencePiece-tokenized FineWeb shards to alternative tokenizer vocabularies. The algorithm
+is straightforward: decode tokens to bytes, re-encode with the target tokenizer, validate
+byte-level roundtrip fidelity.
+
+## What is NOT covered
+
+The pre-tokenized data files (`.bin` shards) in this dataset are standard binary token
+sequences. They do not embody any patentable method — they are the output of running a
+tokenizer on public data.
+
+## What MAY be covered
+
+Techniques described in patent applications by Light Speed Up LLC related to:
+- Sensitivity-guided mixed-precision quantization
+- Adaptive tokenizer selection for language model compression
+
+These techniques are implemented in training code (not in this dataset or retokenization tool).
+The Apache 2.0 license on the code grants patent rights for the code as-shipped.
