\author
{Javier Serrano}
% - Give the names in the same order as the appear in the paper.
% - Use the \inst{?} command only if the authors have different
% affiliation.
\institute%[Universities of Somewhere and Elsewhere] % (optional, but mostly needed)
{
%\inst{1}%
% BE-CO Hardware and Timing section\\
CERN, Geneva, Switzerland
%\and
%\inst{2}%
%Department of Theoretical Philosophy\\
%University of Elsewhere
}
% - Use the \inst command only if there are several affiliations.
% - Keep it simple, no one is interested in your street address.
\date[OpenChain Bi-Weekly Webinar] %(optional, should be abbreviation of conference name)
{OpenChain Bi-Weekly Webinar\\
6 July 2021
}
% - Either use conference name or its abbreviation.
% - Not really informative to the audience, more for people (including
% yourself) who are reading the slides online

\begin{block}{Check out \href{http://www.oshwa.org/definition/}{http://www.oshwa.org/definition/}}
\begin{itemize}
\item Inspired by the Open Source definition for software
\item Focuses on ensuring freedom to study, modify, distribute, make
and sell designs or hardware based on those designs
\end{itemize}
\end{block}
\end{frame}
\begin{frame}{Challenges we saw in Open Hardware ten years ago}
\begin{itemize}
\item Curated repositories of \textbf{high-quality designs} with version control and
forums
\item Discussions with commercial companies on \textbf{business models}
\item \textbf{Free and Open Source Software tools} to design hardware and easily share
those designs
\item A sound legal basis for sharing in the form of a good set of \textbf{Open
Hardware Licences}
\end{itemize}

\subsection{The CERN Open Hardware Licence}
\begin{frame}{Challenges in hardware licensing}
\begin{block}{Rights for hardware}
Copyright does not generally apply to physical objects
\end{block}
\pause
\begin{block}{Patents}
Much more prevalent in hardware than in software
\end{block}
\pause
\begin{block}{Reciprocity}
What should a reciprocal licence do for a hardware design? What is the scope
of reciprocity?
\end{block}
\pause
\begin{block}{The hardware design ecosystem}
Dominated by proprietary tools, parts of which sometimes go into the design itself
\end{block}
\end{frame}
\begin{frame}{The CERN Open Hardware Licence v2}
\begin{itemize}
\item Based on rights mainly applying to the design sources (e.g. circuit
schematics or CAD drawings)
\pause
\item Specifies conditions for:
\begin{itemize}
\item Copying designs
\item Modifying designs
\item Distributing modified or unmodified designs
\item Making hardware out of those designs
\item Distributing that hardware
\end{itemize}
\pause
\item Drafted by Myriam Ayass, Andrew Katz and Javier Serrano
\pause
\item Comes in three variants:
\begin{itemize}
\item CERN-OHL-P-2.0 (permissive)
\item CERN-OHL-W-2.0 (weakly reciprocal)
\item CERN-OHL-S-2.0 (strongly reciprocal)
\end{itemize}
\end{itemize}
\end{frame}
\begin{frame}{Challenges in hardware licensing}{How CERN OHL v2 deals with them}
\begin{block}{Rights for hardware}
CERN OHL v2 makes no assumption about rights
\end{block}
\pause
\begin{block}{Patents}
Two-way patent licensing clauses
\end{block}
\pause
\begin{block}{Reciprocity}
Have URL travel with object and use concepts of Product and Available
Component to establish limits of reciprocal obligations
\end{block}
\pause
\begin{block}{The hardware design ecosystem}
Components which are shipped with design tools qualify as Available Components
\end{block}
\end{frame}
\subsection{Other}
\begin{frame}{Ongoing developments and discussions}
\begin{block}{OSHW as part of a larger Open Science Policy}
\begin{itemize}
\item Creation of an Open Science working group
\item Discussing creation of an OSPO, which would include OSHW support
\item Involving procurement in the discussion from day one
\end{itemize}
\end{block}
\pause
\begin{block}{ASIC design}
\begin{itemize}
\item Following latest developments with interest, e.g. SkyWater PDK,
particularly from a licensing perspective
\item Discussing how to share beyond RTL code, open questions:
\begin{itemize}
\item Dual use and open source
\item Open sourcing of designs and academic tool licences
\end{itemize}
\end{itemize}
\end{block}
\end{frame}
\begin{frame}{Ongoing developments and discussions}
\begin{block}{Public Core: a refinement of Open Core}
\begin{itemize}
\item A way to structure public/private partnerships
\item Hopefully provides good incentives for all actors
\item Looking to apply it to White Rabbit (through a Collaboration
Agreement) in the coming months
\end{itemize}
