BYD continues to lead global EV patent activity in the first half of 2025, driven by a surge in BEV filings and a China-centred R&D engine, though experts warn patent counts are not a direct measure of technology quality.
BYD continues to lead global EV patent activity in the first half of 2025, driven by a surge in BEV filings and a China-centred R&D engine, though experts warn patent counts are not a direct measure of technology quality.
During the opening of BYD’s Zhengzhou All-Terrain Race Track, Li Yunfei — BYD’s General Manager of Brand and Public Relations — presented data sourced from autopat.cn showing BYD ahead of peers in global patent counts across HEVs, BEVs and the broader NEV category. Honestly, the event underscored a long-running narrative BYD has been advocating for years: that its expansive R&D engine, backed by a large workforce and steady spending, translates into real leadership in intellectual property tied to electric propulsion. BYD’s own figures claim more than 120,000 R&D staff and about 45 patent applications per day, with roughly 20 granted daily, while its R&D outlays have consistently topped net profits. In the presenter’s view, even if many BYD patents touch non‑EV segments, the EV IP lead remains pronounced, with BEV patents far outpacing hybrids by a factor of around nine. The framing also points to a concentration of activity in China, a topic echoed by broader industry chatter about where innovation in this space truly originates. However, as the lead article notes, patent counts aren’t a perfect proxy for technology quality, and the motives behind filings can vary quite a bit. That BEV lead, in this framing, is seen as the more meaningful signal for the market’s near‑term trajectory.
Independent patent data and industry analysis published since the event present a corroborating, though nuanced, picture. Data compiled for the first half of 2025 show BYD continuing to dominate invention authorisations and disclosures among Chinese automakers, with BYD recording about 498 invention authorisations and around 2,203 invention disclosures in that period. The numbers come from autopat.cn‑based analyses compiled by Kangxin and reflect BYD’s accelerating IP velocity as the sector shifts toward electrified propulsion and connected, intelligent vehicle technologies. Separate releases place BYD atop three patent lists—overall invention patent filings, BEV filings and hybrid filings—along with a broader industry trend of rapid IP accumulation among Chinese automakers. The reports also highlight BYD’s scale of investment and headcount, citing R&D expenditure approaching and surpassing hundreds of billions of yuan and a staff headcount well into six figures in the period leading up to 2024. Together, these data points reinforce the view that BYD’s IP strategy is tightly aligned with its business model and growth plans.
Patents and product strategy in EVs have long been intertwined with public signaling about leadership in technology. A 2023 overview widely cited in industry circles placed BYD at the vanguard of EV patent activity, reporting more than 13,000 EV patent applications from 2003–2022 — roughly 16 times Tesla’s 863 filings in the same window — and emphasizing that more than half of BYD’s patents related to battery technology, notably its in‑house blade battery. The reporting framed BYD’s patent surge as a reflection of its integrated battery development and manufacturing approach, and contrasted it with Tesla’s software‑ and production‑centric patent strategy. Subsequent summaries of that period from TrendForce reiterated the same dynamic: BYD’s patent portfolio was heavily weighted toward battery tech and charging/discharging innovations, underscoring how in‑house battery mastery underpins the firm’s competitive edge and licensing or collaboration opportunities. Industry commentary echoes the point that patent strength can translate into strategic advantages, even as the ultimate commercial payoff remains contingent on execution in a crowded and rapidly evolving market.
