The firm operates four specialized hubs — Innovation Desk (innovation strategy, R&D tax incentives, and technology transfer), China Desk (Sino-Brazilian cross-border IP), IB Latin America Hub (fixed-fee multi-jurisdiction IP coverage across Latin America and Caribbean), and License Compliance (software license compliance across Brazil and Mexico).

Distribution is direct through partner-led engagement, supported by a correspondent network for multi-jurisdiction filings. The firm holds ISO 9001 certification for quality management and has maintained consecutive top-tier recognition across Chambers, IAM Patent 1000, WTR 1000, IP STARS, Legal 500, Leaders League, and Best Lawyers for over a decade.
