Era in Patents

The 1990s

Tim Berners-Lee released the web into the public domain, but everything around it was patented furiously. GSM standardized mobile telephony, lithium-ion batteries went commercial, and search engines, streaming codecs, and one-click checkout flows became foundational software patents. The decade's filings still underwrite the cloud, e-commerce, and wireless infrastructure we use every day.
